How do you identify the correct moisture level for leather tooling — at the touch-criteria level, not just color?

The color-return heuristic ('case until the leather returns to its natural color') is the most common instruction for wet tooling preparation, and it is insufficient on its own because color return varies significantly by leather type, dye lot, and ambient lighting. The touch-criteria identify the workable window more precisely through three simultaneous assessments. The first is the cool-to-touch criterion: workable wet-tooling leather is distinctly cooler than the surrounding air temperature. This is not a slight difference — the leather is actively evaporating water from the grain surface, which produces a measurable evaporative cooling effect. Room-temperature leather that you can work without distortion feels noticeably cooler than the bench surface or your tool handles. As the leather approaches the dry end of the workable window, the evaporative cooling effect diminishes and the leather begins to feel closer to room temperature. Leather that has dried past the workable window feels the same as room temperature. The cool-to-touch criterion catches the closing window before the visual criterion does. The second is the waxy-matte visual criterion: workable vegetable-tanned leather has a uniform matte surface that looks slightly waxy — not the initial wet-dark appearance of freshly wetted leather, and not the full return to the original dry finish. The transition from wet-dark to waxy-matte is the beginning of the workable window. The transition from waxy-matte back to the original dry finish is the end. Under even lighting, this visual state is reasonably consistent and does not depend on the specific hide color the way that color-return instructions do. The third is the fingernail impression diagnostic: pressing a fingernail firmly into the grain surface and releasing produces three possible outcomes that define the workable range. If the impression fills in within 2 to 3 seconds and disappears completely, the leather is at the wet end of the workable range — tooling will produce clean impressions but the leather may compress under the tool rather than accepting the full depth of the stamp. If the impression remains visible for 10 to 15 seconds and then slowly fades, the leather is in the optimal tooling window — the fibers are relaxed enough to accept the tool without resistance and firm enough to hold the impression cleanly. If the impression has a fuzzy or raised edge rather than a clean compressed groove, the leather has passed the workable window — tooling will produce impressions with undefined edges that may lift slightly as the leather dries. The three-criterion triangle — cool to touch, waxy-matte surface, impression-holds-10-to-15-seconds — is more reliable than any single indicator and more transferable than the color-return heuristic across different leather types and ambient conditions.

How does submersion casing differ from surface wetting for leatherworking, and what does it mean for Patreon documentation?

Submersion casing and surface wetting produce fundamentally different moisture distribution profiles in the leather, which leads to different working windows and different failure modes — and almost no leatherworking tutorial distinguishes between them clearly. Submersion casing saturates the full cross-section of the hide: the grain, the corium (the middle fiber layer), and the flesh side all absorb water. When the leather is removed from water and left to case in a plastic bag or wrapped in a damp cloth, moisture migrates from the saturated corium back toward the grain surface as the grain dries faster. The result is a longer and more consistent working window: as the grain surface dries to the waxy-matte workable state, the corium is still releasing moisture and refreshing the grain from below, extending the working window. Submersion-cased leather typically offers a working window of 20 to 45 minutes depending on leather weight, ambient conditions, and bag-casing duration. Surface wetting — applying water to the grain side only with a sponge, dauber, or spray bottle — saturates only the grain layer and the top portion of the corium. There is no moisture reservoir in the flesh side supplying a slow upward migration. The grain surface reaches the workable waxy-matte state quickly, but it also exits that state quickly because there is no sustained moisture supply from below. Surface-wetted leather typically offers a working window of 8 to 20 minutes, with the outer edge of the window arriving faster and with less warning. A creator who learned wet tooling on submersion-cased leather and demonstrates on surface-wetted leather — or vice versa — will produce timing documentation that is wrong for patrons using the other method. This is the primary source of patron confusion when construction notes say 'I worked the leather for 30 minutes' and the patron finds their surface-wetted piece dry in 12. For documentation: specify the casing method (submersion for how many minutes; surface wetting with which tool and how many passes), the ambient conditions at session time (temperature and relative humidity), and the observed working window duration from the beginning of the waxy-matte state to the first sign of drying edge. A patron in a comparable environment using the same casing method can calibrate directly from this documentation.

What saddle making documentation justifies the professional tier pricing on Patreon?

Saddle making documentation justifies $60 to $80/month professional tier pricing because the information it contains is not available from any other accessible source — not YouTube tutorials, not published books, not trade association resources — and the decisions it documents have direct monetary and safety consequences for working leather workers. Tree selection documentation is the highest-value content. A saddle tree is a structural form that the entire saddle is built over, and its dimensions must match the horse's back or the saddle will not fit, will cause pain and injury to the horse, and will eventually damage itself. Tree selection documentation covers three measurement positions: pommel width measured at the fork between the swell and the bars (expressed in quarter-horse bar, semi-quarter-horse bar, or full-quarter-horse bar categories — each with a specific width range), bar width measured approximately 3 inches behind the pommel where the bars contact the horse's withers (the critical fit measurement), and cantle height and width relative to the seat depth. The bar angle is the twist of the bar relative to horizontal: a horse with pronounced withers and a narrow back requires a higher bar angle than a mutton-withered horse with a flat, wide back. A creator who documents the tree they selected for a specific commission — the horse's measurements, the bar width and angle chosen, and why this tree over the two alternatives considered — is providing the patron with a real fit-assessment framework. The three-point contact assessment is the field fit diagnostic: a correctly fitted saddle contacts the horse's back at the pommel, both rear points of the bars, and nowhere else. Bridging occurs when the tree is too curved for the horse's back — the middle of the bars lifts off, concentrating pressure at the two contact points and creating pain and muscular damage directly under the bars. Rocking occurs when the tree is too flat — the center of the bars contacts the horse's back and the pommel and cantle lift, concentrating pressure in the center and creating instability in the seat. Documenting a fit assessment for a commission saddle — what the creator observed in three-point contact evaluation, what the horse showed in movement in the first ride, and any adjustments made — is curriculum that a working saddler can apply to the next fit evaluation they perform. Rigging position is the documentation that distinguishes craft content from professional content most clearly. The rigging is where the front cinch attaches to the tree, and its position affects how cinch pressure distributes across the horse's barrel. Full-in rigging (positioned directly below the fork) is traditional Western and keeps the cinch pressure forward of the horse's elbow. Three-quarter rigging moves the attachment point 3 inches back, distributing cinch pressure over a wider area and reducing elbow interference on horses with forward-moving elbows. Center-fire rigging places the cinch attachment at the midpoint of the saddle and is used for roping and ranch work where forward cinch pressure causes the saddle to tip forward under a dallied rope. A creator who documents the rigging position chosen for a commission, the horse type it suits, and why a different position was rejected is teaching the patron to think through rigging position as a functional choice rather than a traditional default.

How does the Apple Tax affect leatherworking creator Patreons, and what are specific dollar amounts by content subtype?

Leatherworking creator iOS rates split by content type and consumption context. The workshop consumption pattern — reference use at the bench where a phone or propped tablet may be more accessible than a desktop — reduces iOS rates slightly compared to passive viewing content, but not enough to reduce Apple Tax exposure below significant levels. YouTube leather craft and bag-making tutorials: 55 to 65% iOS. Patrons use the content as reference while building, which creates some desktop and tablet use near the workbench, but initial discovery and passive viewing is primarily mobile. YouTube leather tooling instruction: 50 to 60% iOS. Tooling technique instruction is more technically dense and draws a proportion of desktop viewers who want larger screen real estate for detail work. YouTube saddle making: 45 to 55% iOS. Professional and semi-professional saddle makers tend toward desktop for extended reference use during builds lasting days or weeks. Instagram leather craft and finished bag portfolio: 75 to 85% iOS. Visual craft content is mobile-primary. A leatherworking craft YouTuber at $400/month with 60% iOS faces approximately $72/month ($864/year) in Apple fees beginning November 1, 2026. At $600/month with 60% iOS: approximately $108/month ($1,296/year). At $600/month with 55% iOS (tooling instruction audience): approximately $99/month ($1,188/year). A saddle maker running a professional notes tier at $400/month with 50% iOS: approximately $60/month ($720/year). An Instagram-primary leather bag portfolio creator at $300/month with 80% iOS: approximately $72/month ($864/year). The mitigation is the same across all subtypes: enable Patreon's web-only billing toggle before October 31, 2026, and update YouTube description links and Instagram caption links to the Patreon web URL. Patrons who subscribe through a browser are not billed through Apple. Verify the complete subscription flow from an iOS device before November 1 to confirm the toggle is working correctly.

Patreon for leatherworking creators: complete 2026 guide — wet tooling calibration mechanics, pattern development history, saddle making documentation, and the Apple Tax

Leatherworking Patreons retain when they deliver the calibration data the build video cannot capture: the touch-criteria that identify the tooling moisture window more reliably than color-return heuristics, the three-generation prototype history that explains every seam allowance and hardware choice in the final released pattern, and the fitting documentation that gives saddle making patrons a professional assessment framework rather than a general tutorial. The construction notes format is the primary patron exclusive — what the video presents as a seamless sequence, the notes document as a series of choice points with reasoning.

Creator types and tier structure

Leather craft YouTubers and instructors

Tier structure: Community ($5–8/month, early access to build videos, Discord organized by project type and skill level, monthly tool and sourcing Q&A), Craftsman ($12–18/month, full construction notes for each build — decision points the video presents as a sequence, materials specifications with sourcing notes, tool calibration for specific techniques, troubleshooting guides organized by failure mode at each construction stage), Workshop ($35–50/month capped 10–15, monthly build critique with structured submission protocol — photographs of the completed or in-progress work, the specific question or problem, what the patron has already tried).

The construction notes are the structural differentiator from the YouTube build video. A build video shows the project constructed from cut to finished piece. What it does not show is why each decision was made — why this order of assembly, why this tool at this stage, why this edge finishing approach over the alternatives. The construction notes document these choice points with the reasoning behind them. A patron who has built five projects with construction notes has a decision-making framework they can apply to new projects independently. A patron who has built five projects from videos has experience with five specific projects.

The critique tier works at a price point that signals professional engagement. At $35–50/month capped at 10–15 patrons, the tier generates $350–750/month of recurring revenue from patrons who need individualized diagnosis, not general instruction. The submission protocol is the mechanism that makes critique sessions productive: without it, patrons submit incomplete information and the creator spends session time asking follow-up questions. With the protocol — photographs of the specific problem area, the leather type and weight used, what the patron attempted and what happened — the creator can diagnose from the submission itself and deliver specific recommendations rather than generalities.

Leather bag and accessory designers

Tier structure: Pattern Access ($12–18/month, monthly pattern release with full construction notes and materials specification, growing back-catalog with each new release), Build-Along ($22–30/month, pattern release plus the creator's build-along posts documenting each construction decision as they build the same project, timed to the patron's construction window), Review ($40–60/month capped 8–12, quarterly finished-work review with documented assessment of construction quality and specific recommendations).

Pattern documentation includes three components not present in a purchased pattern: the development history from first prototype through final version, the seam allowance reasoning for each joint type, and the anticipated failure points with how to recognize and recover from them. The development history is the highest-retention content because it explains every decision the patron did not understand at build time. A patron who struggled with the gusset junction step finds the answer in the second-prototype documentation — not because the documentation anticipates their specific confusion, but because it documented why the gusset was designed the way it was, what the earlier version looked like, and what it revealed when it failed.

The back-catalog model is structurally retentive for pattern designers. A patron who has built two patterns from the archive and has a list of three more they want to build faces a much higher cancellation cost than a patron with nothing in progress. The archive becomes a project list rather than a content history, and the value grows with every new release added.

Saddle makers and equestrian leatherworkers

Tier structure: Build Notes ($15–20/month, complete build notes for each saddle commission — tree selection rationale, materials sourcing, tooling documentation, construction decision points), Technical ($35–50/month, full fitting documentation per commission covering tree selection with measurement justification, bar angle rationale for the horse type, rigging position choice and reasoning, skirt construction decisions), Consultation ($65–80/month capped 5–8, quarterly review of patron's in-progress commission work with documented assessment — photographs of fit, assessment of three-point contact, specific recommendations).

Saddle making content has a professional and semi-professional audience that justifies higher tier pricing than general craft content. The people paying $65/month for consultation access are working leather workers — they are spending $65/month to save hours of diagnostic work on a commission where the saddle itself may cost $3,000–8,000 and where a poor fit has professional and reputational consequences. The ROI calculation is clear, which is why the conversion rate at this price point is higher than the comparable rate for general craft content at $35/month.

Leather tooling artists and carvers

Tier structure: Pattern Archive ($10–15/month, monthly carved pattern release with tooling sequence notes and recommended leather specifications), Technique Notes ($20–30/month, full technique documentation per pattern — tool selection rationale, beveling angle and mallet force calibration, swivel knife pressure and cutting depth for each line type, background work sequence to prevent distortion), Critique ($40–60/month capped 8–12, monthly submitted-work critique with healed documentation protocol).

Tooling technique documentation is where the specificity gap between video and notes is widest. A build video can show the tool in motion and the result. It cannot show the creator's internal calibration — the mallet weight they selected for this tool face on this leather temper, the beveling angle they adjusted for the curve versus the straight portion of the same line, the swivel knife grip adjustment that changed the cutting depth for outline versus detail work. These are real-time sensory and mechanical calibrations that happen too fast to narrate and are invisible to the camera. They are exactly what construction notes can document.

Wet tooling calibration mechanics

The standard instruction for preparing leather for wet tooling is to "case the leather until it returns to its natural color." This instruction is accurate as far as it goes. It is not sufficient for a patron who has never used their hands to assess leather moisture state, or for a patron whose leather type, dye lot, or ambient lighting conditions make the color-return threshold ambiguous. The touch-criteria identify the workable window through three simultaneous assessments that work regardless of hide color, dye type, or lighting environment.

The cool-to-touch criterion

Workable wet-tooling leather is distinctly cooler than the surrounding air temperature. This is not a subtle temperature difference — the leather is actively evaporating water from the grain surface, and that evaporative process draws heat from the surface, producing a measurable cooling effect. When you place the back of your hand on workable-window leather, the leather should feel noticeably cooler than the bench surface, your tool handles, or the back of your other hand held in air. The temperature difference at optimal moisture is typically 3–6°C below room temperature in normal studio conditions.

As the leather approaches the closing end of the workable window, the evaporative cooling effect diminishes as available surface water is exhausted. The leather approaches room temperature. When the leather feels the same temperature as the bench surface and your tool handles, it has typically passed the tooling window. A creator who documents "the leather should feel cool when I touch it — if it feels the same temperature as my other hand held in air, it's too dry" gives the patron a criterion that is environment-independent and requires no color reference.

The cool-to-touch criterion catches the closing window before the visual color-return criterion does. Color returns to approximately natural as the leather enters the workable window from the wet side, and continues to dry toward its original texture without a sharp visual transition at the closing boundary. The temperature drop gives approximately 5–8 minutes of warning before the visual color-return approaches its dry-end reference point.

The waxy-matte visual criterion

The grain surface of workable vegetable-tanned leather has a specific visual quality that is easier to recognize with experience than to describe in text — but it can be described precisely enough to give a patron a reference point. The initial wet-dark appearance of freshly wetted or freshly pulled-from-submersion leather is the starting reference: the grain surface appears almost uniformly dark, with a visible wet sheen if cased by submersion. As moisture evaporates from the grain, the surface transitions through the wet-dark stage toward the workable stage. The workable stage is characterized by a uniform matte surface that appears slightly waxy: the color has lightened toward natural but has not yet fully returned to the dry finish texture, and the grain appears closed and slightly compressed rather than open and fibrous the way fully dried leather looks.

This waxy-matte state is not the same as fully dried natural color. Natural-color fully dried leather typically shows open grain texture and a surface that reads as slightly fibrous in raking light. Waxy-matte workable leather reads as smooth, uniform, and slightly compressed in the same raking light. Under ambient light the difference in color may be small, which is why the color-return instruction fails for some patrons — the color return begins at the wet-dark stage and continues gradually through the workable stage and past it. The waxy-matte criterion identifies the middle portion of that color-return gradient, not the endpoint.

The fingernail impression diagnostic

The fingernail test is the most reliable single-point diagnostic for tooling readiness, because it tests the leather's response to compression directly — which is what tooling does. Press a fingernail firmly into the grain surface (use the tip, not the edge, at approximately the same pressure as a moderate stamp) and release immediately. Three outcomes define the workable range:

Outcome 1 — Impression fills in within 2–3 seconds and disappears completely: The leather is at the wet end of the workable window. The fibers are still mobile enough to recover from compression. Tooling in this state produces impressions that are initially clean but may lose definition as they dry, because the fiber recovery continues after the tool is removed. Stamping at this moisture level works but the impression may require deeper force to achieve final depth, or the creator may need to rework the impression after the leather dries slightly. This is a common reason patrons report that their impressions look good immediately after tooling but appear shallow after drying.

Outcome 2 — Impression remains visible for 10–15 seconds and then slowly fades: The leather is in the optimal tooling window. The fibers are relaxed enough to accept the tool without resistance and firm enough to hold the impression during the tooling session. Stamps will produce the full intended depth with normal mallet force, beveling will produce clean compressed edges without tearing, and swivel knife lines will cut cleanly without dragging. This is the state to begin and complete the majority of tooling work.

Outcome 3 — Impression has a fuzzy or slightly raised edge rather than a clean compressed groove: The leather has passed the workable window. The surface fibers have dried and stiffened. Pressing with the fingernail displaces some fibers but the surrounding fibers do not compress cleanly, producing a raised rather than compressed edge. Tooling in this state produces impressions with undefined edges that may appear to have small fiber tears at the edge boundaries. The piece needs to be re-wetted or allowed to case again before tooling can continue.

The diagnostic triangle — cool to touch, waxy-matte surface, impression-holds-10-to-15-seconds — gives three independent assessments that converge on the same workable window. A patron who uses all three criteria has redundant confirmation and is far less likely to encounter the most common wet tooling failure: starting the work before the leather is ready or continuing past the point where the impressions will hold cleanly.

Leather weight effects on timing

Leather weight affects both the duration of the workable window and the time from wetting to workable state. Lighter leathers (2–3oz, commonly used for smaller items like wallets, card holders, and watch straps) contain less water per unit area after wetting and dry more quickly. A 2–3oz piece surface-wetted with a sponge may reach the waxy-matte workable state in 10–15 minutes and remain there for 8–12 minutes before drying past the tooling window in a studio at 68°F and 45–55% relative humidity. Heavier leathers (8–10oz, used for belts, saddlery, and structural bag components) hold more moisture per unit area and take longer to reach the workable state. A submersion-cased 8–10oz piece may take 30–45 minutes to case fully and may remain in the workable window for 20–35 minutes in the same studio conditions. Documentation that specifies the leather weight and the casing method allows a patron to calibrate their timing expectations before beginning. A patron who reads "I worked this 3–4oz piece for 25 minutes" and attempts the same timeline on a 3–4oz piece surface-wetted with two sponge passes will find their piece dry at 15 minutes. A patron who knows to specify that the creator submersion-cased their 3–4oz piece for 20 minutes will understand why the working window was longer.

Re-wetting and recovery

Over-wet leather — leather that is still at the dark-wet stage when tooling begins — produces impressions that drift as they dry. The correction is to allow the piece to case without tooling until the waxy-matte stage is reached. A piece that was over-wetted can typically be recased in a plastic bag for 15–20 minutes to allow moisture to redistribute and the grain to return to the workable state, unless the grain was already damaged by premature tooling. Over-dry leather — leather that has passed the workable window — can be re-wetted, but the approach matters. Applying water with a sponge or spray bottle to a piece that was over-dried creates a new wet-dark stage that requires the full casing time to return to workable. A more efficient approach for small areas that have dried while the creator is still working: a clean water brush applied very lightly to the specific area, allowed to absorb for 2–3 minutes, followed by the fingernail test to assess recovery. The surrounding areas that are still in the workable window are left without additional moisture — spot re-wetting returns the dried area to workable without extending the moisture state of surrounding areas that are still correctly tempered.

Pattern development history

Most bag and accessory pattern releases document the final version. The final version is the outcome of a design process that encountered problems, made corrections, and made tradeoffs — none of which are visible in the released pattern pieces and construction notes. The patron who encounters a difficulty at a specific step does not know whether they made an error, whether the step is genuinely difficult and the difficulty is expected, or whether there is a better approach the creator discovered and kept private. Development history documentation makes the path visible.

The three-generation prototype sequence

Most bag designs that go through a rigorous development process require three prototype generations before the final release pattern is accurate and the construction sequence is fully documented. Each generation answers a different category of question.

The first-generation prototype is the dimension-check prototype, typically built in low-cost upholstery leather, heavy canvas, or craft-store vegetable-tan at a weight that approximates the final leather but costs less than 20% of the final hide cost. The dimension-check prototype answers one question: do these dimensions produce the finished shape the design intends? The documentation from the first prototype covers what the check revealed (the bag body proportion was correct but the flap dropped 15mm lower than the base of the bag, so the flap closure was obstructed when the bag was set down; the pocket placement created a seam line directly over the handle attachment hardware, preventing the hardware from seating flush against the leather) and what was adjusted before the second prototype (the flap was shortened 20mm; the pocket was moved 30mm toward the top edge of the face panel). The first prototype documents what was wrong, not just what the final version corrected.

The second-generation prototype is the construction-sequence prototype, built in mid-grade leather at or near the final weight. It answers a different question: does this assembly sequence work, or does one step prevent the next from being completed cleanly? The construction-sequence documentation is the most valuable development history content for patrons, because it records the steps that had to be reordered and why. A specific example that is common in structured bag construction: the magnetic closure was originally installed as the last step before the zipper was sewn. At that stage, the closure stud needed to be positioned through the body panel and fixed with the backing plate — but the body panel was already attached to the gusset, which made it impossible to reach behind the panel to seat the backing plate flush. The sequence was revised so the magnetic closure is installed in the body panel before the gusset is attached. This is the kind of sequence knowledge that an experienced maker carries as implicit memory and that a patron has no way to derive from the pattern instructions alone. It is also the single most common category of patron construction failures: errors introduced not by incorrect technique but by performing correct techniques in the wrong order.

The second prototype is also where hardware specifications are tested against construction reality. A D-ring in a folded tab is a standard handle attachment method, but if the leather weight at the fold creates a combined thickness that prevents the specified Chicago screws from reaching across, the hardware specification fails at construction time rather than at design time. The documentation records what hardware was specified, what problem it created (the 12mm Chicago screws specified could not reach across a 9mm fold on 4–5oz leather; 16mm screws were tested but the post projected through the back face and created a structural point risk), and what was substituted (rivet-mounted rectangular rings through a single-thickness reinforcement patch glued and sewn to the back face, distributing the load without the fold thickness problem). A patron building from the pattern who sees the rivet-mounted rectangular rings without the development history will wonder why the common folded-tab construction was not used. The development history answers the question.

The third-generation prototype is the finishing prototype, built in the final specified leather at the final hardware specification. It answers whether the specified materials work together, whether the edge finishing approach is achievable, and whether the finished piece holds up under realistic use testing. Edge finishing documentation from the third prototype is specifically useful for patrons: which edges can be burnished to a clean result, which require edge paint because the leather fiber structure at the cut edge does not respond well to burnishing (many vegetable-tanned shoulders have a more fibrous corium than belly or back cuts and resist clean burnishing), and what the finishing sequence was — whether the inside edges of internal pocket panels were finished before or after the pocket was sewn in, and why (internal pocket edges finished after assembly are accessible only through the pocket opening and require a finishing tool narrow enough to fit, which is a constraint the third prototype documents by discovering it).

Seam allowance documentation

Seam allowances in leather are not standardized the way they are in fabric sewing. Different joint types require different allowances, and the choice of joint type has consequences for the finished piece's edge thickness, visual weight, and durability. The development history documents these choices. A skived and overlapped seam (where the edge of one panel is thinned on the back face and overlapped onto the front face of the mating panel) requires an allowance equal to the overlap width plus the thickness lost to skiving. A butt joint (two panels meeting at their edges with stitching through both) requires no allowance but creates a combined edge thickness at the seam equal to both panels, which may be incompatible with the finished edge finishing approach if the combined thickness makes burnishing difficult. A fold-over seam (where one panel edge is folded over the mating edge and glued before stitching) requires an allowance equal to the fold width plus the thickness of both folded layers. Documenting why a specific joint type was chosen at a specific seam — and what the alternative would have required — gives the patron the judgment framework to modify the pattern for different leather weights without replicating the same seam choices the original design required.

Saddle making professional documentation

Saddle making has been documented in published resources at the general technique level for decades. What is not documented at the level that practicing saddlers need is the specific decision reasoning for individual commissions: why this tree for this horse, why this rigging position for this rider's intended use, why this skirt pattern rather than the alternative. The Patreon tier that captures this reasoning charges professional prices because it delivers professional value — the patron is not watching a hobbyist build a saddle, they are observing a working saddler think through a commission.

Tree selection documentation

A saddle tree is the structural framework the saddle is built over. Its dimensions must match the horse's back or the saddle will cause pain, damage muscle and skin, and eventually damage the tree itself from the load distribution it was not designed to carry. Tree selection documentation covers three measurement positions, not one. The pommel width — measured at the fork between the swell and the bars — is the first measurement and the one most commonly referred to in general resources. It is expressed in the bar category system: semi-quarter-horse bar (approximately 6.5 to 6.75 inches measured at the standard 90-degree angle to the bar), quarter-horse bar (approximately 6.75 to 7 inches), and full-quarter-horse bar (approximately 7 to 7.25 inches). These categories describe the width at one position on one horse-back shape, but they do not fully describe the tree fit — a quarter-horse bar tree may fit a horse with moderate withers but the same bar width with a different angle will not. The bar angle — the angle the bars make with horizontal when the tree is placed on the horse's back — is the second measurement. A horse with high, pronounced withers needs a higher bar angle to clear the withers without pressing on them; a mutton-withered horse with a flat, wide back needs a lower bar angle so the bars contact the back rather than bridging over the top. A creator who documents "I selected a quarter-horse bar tree at 93 degrees of bar angle — the horse's withers are moderate but defined, and at 90 degrees the bars bridged over the withers; at 95 degrees the bars sat flat on the withers and would have concentrated pressure there" gives the patron a fit assessment reasoning process, not just a tree category. The bar width measured 3 inches behind the pommel at the bar-to-withers contact point is the third and most critical measurement for fit. This is where the bars contact the horse's muscles directly below the withers — the highest-pressure contact zone. Documentation of this measurement for each commission tree gives the patron a reference for what bar-to-contact dimensions produced a well-fitting saddle on a documented horse type.

Three-point contact assessment and common problems

A correctly fitted saddle contacts the horse's back at three points: at the pommel bars on both sides of the withers, and at the rear points of the bars. The center of the bars between these points should have no contact — the tree should span the horse's back from front contact to rear contact without pressing on the muscles in between. Assessing three-point contact requires placing the bare tree on the horse's back (no pad, no flocking) in the position the finished saddle will sit and observing the contact pattern from behind and from each side. The assessment documentation records what was observed, not just the tree category chosen.

Bridging is the most common fit problem on horses with a strong back curve: the bars contact the front and rear but lift off the middle of the back, concentrating pressure at the contact points and leaving the center of the back unloaded. A bridging tree on a horse with a pronounced back curve creates pain directly under the front and rear bar contacts and may cause the horse to hollow its back during work. The documentation records the bridging assessment — "at initial placement the rear bar points were in contact but the front bars were 20mm off the back at the position immediately behind the wither shelf; a tree with a slightly greater curve in the bar would be the correct fit; after evaluating two additional trees, the second had the appropriate curve — the gap at the wither shelf closed to approximately 3mm, which will close completely under the rider's weight" — and gives the patron a diagnostic framework for recognizing and correcting bridging in their own fit assessments.

Rocking is the inverse problem, common on horses with a flat, relatively straight back: the center of the bars contacts the horse and the front and rear points lift. A rocking tree concentrates pressure in the center of the back and creates instability in the seat — the rider perceives this as a saddle that does not feel planted. Documentation of a rocking assessment and its resolution (selecting a tree with a longer, flatter curve in the bar, or using a treeless design for very flat-backed horses) gives the patron the corresponding diagnostic framework.

Rigging position documentation

The rigging position determines where the front cinch attaches to the tree, and it affects how cinch pressure distributes across the horse's barrel. Full-in rigging — the attachment point positioned directly below the fork — is traditional Western rigging and places the cinch directly at the front of the horse's barrel, forward of the elbow. Three-quarter rigging moves the attachment point approximately 3 inches behind the fork, which shifts cinch pressure slightly rearward and distributes it across a wider area of the barrel. This position reduces elbow interference on horses with forward-moving elbows and is the most common choice for all-around Western use. Seven-eighths rigging, between full-in and three-quarter, is a midpoint choice for horses with moderate elbow clearance requirements. Center-fire rigging positions the cinch attachment at the midpoint of the saddle's bottom, which places the cinch well behind the elbow and distributes pressure toward the center of the barrel. Center-fire was traditional for roping saddles because it prevents the saddle from tipping forward under the load of a dallied rope on a stopped horse. Documenting the rigging position chosen for a commission, the horse type and intended use that justified it, and what alternative was considered and rejected gives the patron the reasoning behind what is often presented as a traditional choice rather than a functional decision. A patron who reads "I chose three-quarter rigging rather than full-in because this horse's elbows contact the cinch at the front barrel position — I observed this in motion before the fitting session — and full-in rigging would have created consistent elbow interference" learns to observe elbow clearance as part of a pre-fitting assessment.

Apple Tax for leatherworking creator audiences

Leatherworking creator iOS rates reflect the workshop consumption pattern. Patrons use tutorials and construction notes as reference while building, which creates some desktop use near the workbench — but this pattern reduces iOS rates only modestly compared to passive-viewing content, because initial discovery and non-reference use is still primarily mobile.

YouTube leather craft and bag-making tutorials: 55–65% iOS. Patrons who use the content while building may access it on a propped tablet or laptop at the bench, but discovery viewing and bookmarked reference use is predominantly mobile. YouTube leather tooling instruction: 50–60% iOS. Tooling instruction content is more technically dense and draws a proportion of desktop viewers who want larger screen detail. YouTube saddle making and equestrian leather: 45–55% iOS. The professional and semi-professional audience trends toward desktop for extended reference during commissions. Instagram leather craft and completed bag portfolio: 75–85% iOS. Visual finished-work content is mobile-primary in all craft categories.

Specific dollar amounts at 30% Apple fee rate on the iOS-billed portion, beginning November 1, 2026:

A leather craft YouTuber at $400/month with 60% iOS: approximately $72/month ($864/year). At $600/month with 60% iOS: approximately $108/month ($1,296/year). A leather tooling instructor at $500/month with 55% iOS: approximately $82.50/month ($990/year). A saddle making professional notes creator at $400/month with 50% iOS: approximately $60/month ($720/year). An Instagram-primary leather bag portfolio creator at $300/month with 80% iOS: approximately $72/month ($864/year).

The mitigation is the same for all: enable Patreon's web-only billing toggle before October 31, 2026. Update YouTube description links to Patreon web URLs rather than app deep links. Update Instagram caption links and any Linktree positions to web URLs. Verify the complete subscription flow from an iOS device before November 1 to confirm the toggle is functioning. Patrons who subscribe through a browser are billed through Stripe, not Apple — the 30% fee never applies.

For the saddle making professional tier audience: the iOS rate is lower (45–55%) because the professional and semi-professional audience uses desktop for extended reference work. But even at 50% iOS and $400/month, the $60/month ($720/year) annual exposure is meaningful on a $4,800/year gross revenue stream. The web-only toggle is worth enabling regardless of tier price or iOS rate.

The leatherworking Patreon tier overview covers the core tier structures across subtypes. For the Apple Tax calculation specific to your current Patreon revenue and iOS rate, the KeepTier calculator takes two inputs and returns the specific monthly and annual fee exposure. For the full Apple Tax explainer including the three worked receipts and the two platform escape hatches, the blog post covers those in detail. KeepTier plans start at $9/month — a self-hosted membership page with 0% platform fee, Stripe Checkout, and no Apple Tax exposure.
