Finger loop braiding tutorial videos demonstrate the hand motions: how the fingers insert through loops, how a target loop is retrieved, how the braid grows pick by pick between the two hands. What they cannot demonstrate is the structural logic beneath those motions — why the working finger must pass through all the intervening loops before reaching the target loop and why that passage is what creates the interlacement, why capturing the upper leg of a target loop rather than the lower leg determines which face of the finished braid that element appears on, why the direction of the single outermost exchange on each side of the working width is the only variable separating a tube braid from a flat band, why a single incorrect edge exchange can convert the entire braid structure from tube to flat from that pick forward rather than creating a localized cosmetic error, and why complete documentation of a finger loop braiding sequence requires specifying the finger assignment, the leg orientation, and the pick-up direction of every exchange rather than just the working order of the fingers. These properties are mechanical and invisible to a camera recording hand motion. A patron who knows the stitch sequence but not the structural mechanics cannot diagnose why their braid collapsed from a tube to a flat section, cannot determine whether their documentation is specifying upper-leg or lower-leg capture for a given exchange, and cannot explain to themselves or to others why two superficially similar exchange sequences produce structurally different braid categories. This post documents the mechanical layer.

How the shed forms in finger loop braiding: the working finger, the intervening loops, and the upper-leg versus lower-leg pick-up

Finger loop braiding requires no tool other than the braider’s own hands. Each loop of thread is draped over one finger so that the upper leg of the loop — the strand that will be on top when the hand is held with its dorsal surface facing upward — passes across the back of the hand, and the lower leg hangs below the finger toward the palmar side. In a standard setup for a five-loop braid worked by two people or by one person using both hands, one loop is held on each of the four working fingers (index, middle, ring, and little finger) of one hand, with the fifth loop on a finger of the other hand; or the loops are distributed two or three per hand depending on the braid count. The exact distribution varies by tradition, by braid pattern, and by the number of loops in the sequence, but the fundamental arrangement is always the same: one loop per finger, each loop presenting two legs to the braider.

The shed in finger loop braiding is formed by the working motion itself, not by any pre-positioned device. When a working finger is about to retrieve a target loop, it must first pass through all the loops held on the fingers between itself and the target. This passing-through is not incidental — it is the structural event that creates the interlacement. As the working finger travels from its starting position toward the target finger, it physically pushes through the loops on every intervening finger. Those intervening loops are temporarily displaced by the working finger’s passage. When the working finger completes the retrieval and returns to its starting position, pulling the target loop with it, the target loop passes back through all those same intervening loops in the opposite direction. The result is that the retrieved loop is interlaced through every intervening loop — over or under each one depending on the specific geometry of the passage — and one complete interlacement cycle has been added to the growing braid structure.

This shed-formation mechanism is fundamentally different from the two most commonly compared alternatives: tablet weaving and inkle loom weaving. In tablet weaving, each card (tablet) holds a small group of warp threads threaded through its four corner holes. The shed is formed by rotating the cards — a quarter-turn forward or backward — which twists the warp threads held in each card and raises some threads relative to others, creating a mechanical opening through which the weft is passed. The shed is determined entirely by the card rotation sequence and the threading arrangement through the card holes; the weaver does not physically pass a working element through the warp threads. In inkle loom weaving, the shed is created before weaving begins by threading alternate warp threads through heddle loops (which hold them in a fixed raised position) and leaving the remaining threads as non-heddle threads (which hang below the heddle line). The weaver opens the shed by pressing down on the non-heddle threads to separate them from the heddle threads. Again, the shed is maintained by a mechanical device and the weaver exploits it rather than creating it dynamically. In finger loop braiding, there is no pre-positioned shed and no mechanical device — the working finger opens the shed dynamically by passing through the intervening loops at the moment of retrieval and the shed closes as the finger withdraws.

The pick-up direction — whether the working finger captures the upper leg or the lower leg of the target loop — determines which face of the finished braid the retrieved element appears on. If the working finger approaches the target loop from below the plane of the working loops, inserts upward through the intervening loops, and hooks the lower leg of the target loop (the leg that was hanging below the target finger), the retrieved loop element will appear on one face of the braid. If instead the working finger approaches from above or to the side and captures the upper leg of the target loop (the leg that was resting on the dorsal surface of the target finger), the retrieved element appears on the opposite face. Pattern effects in finger loop braiding — alternating colors on the surface, diagonal stripes, chevron patterns — are produced by systematically varying which leg is captured on which exchange across the sequence of picks. A documentation specification that says only “retrieve loop from right index finger” without specifying upper or lower leg is ambiguous at exactly the point where it needs to be precise.

After the working finger has captured the target loop by its designated leg, the finger returns to its starting position while holding the retrieved loop. This return journey is the second half of the interlacement event: the retrieved loop travels back through all the intervening loops that the working finger passed through on the outward journey, passing through each of them from the opposite side. When the working finger arrives back at its starting position, the retrieved loop is fully interlaced through all intervening loops, and the working finger releases the loop it was carrying from the previous pick and takes on the retrieved loop as its new holding loop. The exchange is complete: the target finger is now holding the loop that was previously on the working finger, and the working finger is holding the loop that was previously on the target finger. The braid has grown by one pick.

For Patreon documentation, the mechanical consequence of this system is that the notation must be complete at the level of every pick. Unlike a tablet weaving documentation that can specify “forward four turns, backward four turns” as a repeating sequence summary, or an inkle loom pattern that can be specified by a warp threading plan, finger loop braiding documentation must specify, for every pick in the sequence: the identity of the working finger, the identity of the target finger, and the leg (upper or lower) being captured. These three data points are the minimum information required to reconstruct any exchange. Omitting any one of them leaves the patron with an ambiguous instruction that will produce a correct or incorrect result depending on which assumption they make to fill the gap.

Tube braids versus flat bands: why the outermost exchange direction is the structural determinant

The most practically consequential structural distinction in finger loop braiding — the one most likely to produce a visibly wrong result when misunderstood — is the distinction between tube braids and flat bands. Both are produced using the same fundamental exchange mechanism (working finger through intervening loops, retrieves target loop by a designated leg). Both use the same starting configuration of loops on fingers. The difference between them is produced entirely by the direction of the exchange at the outermost position on each side of the working width.

In a tube braid, the outermost exchange on each side sends its loop inward — toward the center of the working width rather than across to the other hand. On the left side, the loop on the leftmost working finger (for example, the left index finger) is retrieved by a finger from the right hand that has passed inward across the working width. On the right side, the loop on the rightmost working finger is retrieved by a finger from the left hand passing inward. After each complete exchange cycle, every loop has moved one position closer to the center, and the outermost loops have crossed under or over the inner loops rather than traveling across the full width to the other hand. Because both edges of the working width are directing loops inward, the braid structure wraps around itself symmetrically and the two working edges are joined to each other by the loop paths. The finished structure is a hollow tube with no free selvedge edges — both edges are closed by the inward-traveling loop elements.

The simplest tube braid — the structure sometimes called kongo gumi or the one-loop braid in Western finger loop braiding traditions — uses a single loop worked on both hands simultaneously. Each hand holds one leg of the loop. The working motion exchanges the positions of the two legs, building the cord structure pick by pick. Even at this simplest level, the “inward” character of the exchange is present: the loop on one hand passes to the other hand by moving through the space between the hands, not by traveling across to a third position. More complex tube braids use two, three, or four loops per hand, and the inward exchange direction at both edges is what maintains the tube closure in all of them.

In a flat band, the outermost exchange on one side sends its loop all the way across to the opposite hand rather than inward. The loop on the leftmost position of the left hand is retrieved by the rightmost finger of the right hand, and it travels the full working width. After this cross-width transfer, that loop is now on the far right of the working setup. The opposite selvedge exchange also crosses to the far side. Instead of wrapping around itself, the braid grows as a flat strip. The loops that were at the left edge are now at the right edge; they will make their way back to the left edge through successive exchanges in subsequent picks. The edge loops in a flat band are structurally equivalent to the selvedge threads in warp-faced weaving: they are the elements that define the lateral boundary of the structure and whose consistent path at the edge determines the quality of the selvedge.

The key structural fact that tutorial videos cannot convey is why these two different behaviors arise from what looks, from a camera angle above the working hands, like a similar set of hand motions. Both tube and flat band braiding involve fingers passing through loops and retrieving target loops. The difference is invisible in the hand motion itself: it appears only in which finger retrieves which loop at the outermost position and whether that retrieved loop travels inward or all the way across. To see this distinction in a video, the viewer would need to track the path of a specific loop element pick by pick and notice that in the tube setup it stops at an interior position while in the flat band setup it continues to the opposite side. This level of frame-by-frame element tracking is not what tutorial video production supports, and it is not what casual viewing achieves. The mechanical explanation must be written down.

The consequence for starting-loop distribution: a tube braid and a flat band of the same total loop count do not use the same starting distribution across the fingers. A five-loop tube braid and a five-loop flat band have different initial arrangements because the exchange sequences they require have different structural requirements at the edges. A braider who sets up the loops for a tube braid and then attempts to work the exchange sequence of a flat band will produce an incoherent structure — neither tube nor flat — because the loop distribution is wrong for the exchange sequence. Getting the initial distribution right is a prerequisite for getting the exchange sequence right, and the documentation must specify both.

Loop notation and documentation requirements: specifying the complete braiding state

The documentation challenge in finger loop braiding is that the complete state of the braiding setup at any point in the sequence is more complex than the documentation conventions commonly used for comparable textile techniques. In tablet weaving, the full state at any step is specified by the card threading (which threads are through which holes) and the turn history (how many forward and backward turns each card has made). In inkle loom weaving, the full state is specified by the warp threading plan (which threads are heddle and which are non-heddle) and the pick count. In finger loop braiding, the full state at any step requires knowing: which loop is currently on which finger, which leg of each loop is the upper leg (since the loops can be twisted — transferred in a way that reverses which leg is on top), and for the next exchange, which leg the working finger should capture. Specifying just the loop order on the fingers is insufficient if the leg orientations have changed during the sequence.

Historical researchers, including those working within the LMBRIC (Loop and Multi-Bobbins Research and Innovation Circle), have developed formal notation systems specifically for finger loop braiding documentation. These systems encode the full braiding state in a compact form that can be written alongside the exchange sequence. A typical notation entry specifies the exchange step as a pair of positions (working finger, target finger) followed by a leg indicator (U for upper leg, L for lower leg) and a direction indicator (I for inward exchange in a tube braid setup, X for cross-width exchange in a flat band setup). A complete step entry in this notation looks like: “LI › RI : U : I” meaning the left index finger retrieves the loop from the right index finger, capturing the upper leg, with an inward exchange direction. A different entry, “LI › RM : L : X”, means the left index finger retrieves the loop from the right middle finger, capturing the lower leg, with a cross-width exchange.

Voice-memo notation adapts the same information for real-time recording without stopping the braiding session. The phonetic shorthand “L1 picks up R2 lower” encodes the same content as a formal notation entry: L1 (left index finger) retrieves from R2 (right index finger) by capturing the lower leg. A braider working through a complex sequence for the first time can dictate each exchange step as it is performed, recording the audio on a phone, and then transcribe the sequence into written notation afterward. This method allows documentation of novel sequences without the distraction of stopping to write after every pick — the braiding flow is maintained and the notation is recovered from the audio recording. For Patreon content creators developing new patterns, voice-memo notation is the practical intermediate step between “I just braided something interesting” and “I have a written pattern I can publish and support.”

The leg-orientation state adds a layer of complexity that is easy to overlook when learning from video tutorials. During normal braiding, a retrieved loop is placed on the working finger in a specific orientation: the leg that was captured in the retrieval becomes the new lower leg on the working finger, and the other leg becomes the new upper leg. If a retrieval is performed in the direction that reverses this orientation — for example, if the working finger approaches from the opposite angle and the captured leg ends up as the upper rather than lower leg on the working finger — the loop is said to be twisted. A twisted loop held on a finger has its upper and lower legs reversed relative to an untwisted loop. If the next exchange captures what the documentation specifies as the “upper leg” of that loop, the braider who performed a twisted retrieval will be capturing the leg that is functionally in the lower position, producing the opposite face assignment from what the documentation intends. The notation system must either prevent twisting by specifying the retrieval direction precisely enough to enforce the correct orientation, or must explicitly track whether each loop is in an untwisted or twisted state at each step.

Pattern documentation for a Patreon post therefore must specify at minimum: the number of loops in the sequence, which fingers the loops start on in the initial setup, the leg orientation of each loop at setup (which leg is upper, which is lower), and the complete exchange sequence specifying working finger, target finger, and pick-up leg (upper or lower) for every exchange. For sequences with more than five or six exchanges before the repeat, the documentation should also include a state table that shows the loop distribution and leg orientation after each exchange, so that a patron who makes an error can return to a known good state by checking their current configuration against the table rather than having to unwork the entire sequence from the beginning.

The consequence of a single missed or incorrect exchange illustrates why this level of documentation specificity matters. In tablet weaving, if a braider skips one turn of one card, the warp threads in that card create a localized distortion — a small color error or texture interruption at that point in the pattern — but the surrounding cards, which were turned correctly, continue to hold the braid structure in position. The error is cosmetic and local. In finger loop braiding, an incorrect exchange at the outermost position of the working width — even a single incorrect exchange — can convert the entire structure from tube to flat or from flat to tube from that pick forward, because it is the outermost exchange direction alone that determines the structural type. The error is not cosmetic and not local: it is structural and propagates into every subsequent pick until the braider detects it and unworks back to the error point.

Historical examples and traditions: Tudor points, Japanese kute-uchi, Andean fragments, and the SCA community

Finger loop braiding is not a recent craft revival — it is one of the oldest documented hand-textile techniques in multiple independent cultural traditions, and its historical record spans centuries and continents. Understanding the historical context is directly relevant to Patreon content creation because the largest active practitioner community for finger loop braiding is rooted in historical reenactment and reconstruction, and that community has high expectations for technical accuracy and historical sourcing in the content it will pay to access.

In Tudor England, finger-loop braids were a functional textile product used throughout the 15th, 16th, and 17th centuries under the name “laces” or “points.” The term “lace” in this historical context means a braided cord — specifically a narrow, firm cord used to fasten garments at their joinings: attaching sleeves to bodices, fastening hose to doublets, closing the front of a gown, and similar functional connections that modern clothing achieves with buttons, zippers, and snaps. The term does not refer to openwork lace in the modern sense. Points were threaded through pairs of eyelets and tied, providing adjustable closures at multiple points on the garment. They were also used as hat bands, decorative trim on book bindings, and functional ties in a wide range of domestic contexts. Researchers including those who have studied extant artifacts in museum collections and period illustrations have reconstructed the specific loop braiding techniques used to produce Tudor points, identifying the loop counts, exchange sequences, and materials (typically silk, wool, or linen thread) from surviving examples and technical descriptions in period sources.

The Japanese tradition of kute-uchi (also written as kumiuchi or, in the form of the characters used in historical technical texts, in ways that modern romanization renders variously) is the best-documented historical loop braiding practice in terms of surviving technical texts. Japanese kute-uchi produces braids with complex geometric patterns from the interaction of different colored loops across multi-finger sequences. The Japanese tradition developed its own notation system, recorded in technical manuscripts that describe finger assignments, loop counts, and exchange sequences in terms that scholars have been able to reconstruct and verify by producing the described braids. The braids produced by kute-uchi sequences are structurally identical to those produced by the Western European finger loop braiding tradition — both are based on the same fundamental mechanism of loop exchange through intervening loops — despite having been developed independently in separate cultural contexts. The convergence of two independent traditions on the same mechanical solution speaks to the elegance and naturalness of the loop exchange shed-formation mechanism: given threads looped over fingers and two hands facing each other, the loop exchange braid is one of the most intuitive structures a person could develop without any tool beyond their own hands.

In the Andean textile tradition, finger loop braiding appears in pre-Columbian fragments that can be identified by the characteristic interlacement structure that loop braiding produces at the microscopic level. Unlike tablet weaving or warp-faced loom weaving, which produce distinctive interlacement geometries of their own, loop braiding creates an interlacement pattern in which each element traces a path consistent with having been retrieved by a finger passing through a stack of intervening loops. When researchers examine ancient Andean textile fragments under magnification, the element paths that are consistent with loop braiding production — as opposed to other cord-forming techniques — can be identified even when the original production context is unknown. The structural evidence in the fiber itself is sufficient to distinguish loop braiding from the alternatives. For Patreon content focusing on the Andean tradition, this point — that the technique can be identified from the artifact rather than requiring a textual description — is precisely the kind of technically grounded detail that distinguishes high-quality historical documentation from general craft content.

The SCA (Society for Creative Anachronism) and historical reenactment community currently represents the largest active practitioner community for period-accurate finger loop braiding outside of Japan. SCA participants who are reconstructing historical garments for specific periods — Tudor, Elizabethan, medieval European — need accurate technical documentation of the correct loop braiding techniques for their period and region. Points for a Tudor doublet must use the materials, loop counts, and exchange sequences that would have been used historically, not a modern simplified approximation. Hat bands, book ties, and decorative trim similarly require period-accurate construction for the garment or object to be historically authentic. Patreon content for this community has high reference value: patrons are actively reproducing historical objects and need documentation that is correct enough to produce a verifiable result. A patron who pays for a pattern and follows it correctly expects to produce a historically accurate braid, not merely a decorative cord.

The overlap between the Tudor and SCA communities and the Japanese kute-uchi research community is significant: the same underlying mechanical technique connects these traditions, and researchers working on one tradition often contribute to understanding of the others. For Patreon content creators, this cross-traditional interest means that well-documented historical patterns can attract patrons from multiple reenactment communities simultaneously — a Tudor points pattern that includes a clear mechanical explanation of the exchange sequence will be of interest to Japanese textile historians, Andean textile researchers, and SCA participants alike, not just to Tudor reenactors specifically.

The Apple Tax for finger loop braiding creators from November 2026

Finger loop braiding has an active content community on YouTube, Instagram, Pinterest, and Facebook, with significant overlap with historical reenactment, SCA costuming, Tudor and medieval textile reproduction, and historical fiber arts broadly. The audience for finger loop braiding content is heavily mobile-first, consistent with the broader historical craft and needlework demographic. The historical and reenactment angle reinforces the mobile-first pattern: patrons frequently use Pinterest for visual reference research and Instagram for process documentation, both of which are primarily mobile discovery platforms. iOS proportions for finger loop braiding content by platform: YouTube tutorial channels covering medieval craft, historical fiber arts, and loop braiding technique 65–78% iOS; Instagram historical needlework and fiber arts process documentation 68–80% iOS; Pinterest historical textiles, Tudor accessories, and loop braiding project boards 72–84% iOS; Facebook medieval reenactment and historical fiber arts groups 60–74% iOS.

Finger loop braiding instructors on Patreon typically offer documentation packages that go substantially beyond what a free tutorial video can convey: complete loop-notation sequences for specific historical braids with exchange-by-exchange state tables, material specifications for period-accurate reproduction (thread counts, fiber types, sources for period-compatible thread), project guides for specific historical applications (Tudor points with correct eyelet placement and tying instructions, hat bands with period-accurate width and stitch count, book ties and garment trims for specific regional and temporal contexts), and troubleshooting guides for common errors including the tube-to-flat structural conversion and the twisted-loop leg-orientation problem. The technical specificity of this documentation — and the impossibility of deriving correct exchange sequences, leg orientations, and historical material specifications from generalist tutorial videos — makes finger loop braiding Patreons high-retention subscriptions for patrons who are actively producing period-accurate work. The patron is not watching casually; the patron is working from the documentation, checking each step against the notation, and needing to know that the documentation is correct and complete.

Monthly revenue for active finger loop braiding instructors on Patreon ranges from approximately $50–$75 per month for smaller channels focused on one tradition or one braid type, and $100–$175 per month for established instructors with comprehensive multi-tradition documentation archives. Many finger loop braiding instructors combine this technique with adjacent historical fiber arts — naalbinding, tablet weaving, inkle weaving — rather than maintaining a single-technique focus, which tends to increase both patron count and revenue for the multi-technique archive.

Three representative Apple Tax calculations using the 30% × iOS percentage formula: at $75 per month with 70% iOS (a smaller YouTube-primary instructor reaching Tudor reenactors and SCA costumers): $75 × 0.70 × 0.30 = $15.75 per month ($189 per year) going to Apple rather than to the creator. At $125 per month with 74% iOS (a mixed-platform instructor with YouTube, Instagram, and Pinterest content reaching both SCA participants and Japanese kute-uchi researchers): $125 × 0.74 × 0.30 = $27.75 per month ($333 per year). At $200 per month with 76% iOS (an established historical fiber arts instructor with a comprehensive multi-tradition pattern archive, Pinterest-primary discovery audience, and strong SCA community connection): $200 × 0.76 × 0.30 = $45.60 per month ($547.20 per year) from November 1, 2026.

The mechanism behind these losses is Apple’s App Store commission rule: any subscription sold through an iOS app must pay Apple a 30% commission before the creator receives the remaining 70%. Patreon’s iOS app processes new patron subscriptions through Apple’s in-app purchase system, which triggers this commission. From November 1, 2026, Patreon passes this 30% cost directly to creators rather than absorbing it as a platform cost. A patron subscribing to a $5 tier through the Patreon iOS app sends $1.50 to Apple — $18 per year — before the creator receives anything. A patron subscribing to a $10 tier through the app sends $3 per month to Apple — $36 per year. For a creator with thirty patrons at $5 and ten at $10, the November 1 cutover means $45 per month — $540 per year — begins going to Apple rather than to the creator, assuming typical iOS subscription proportions.

The fix is web-only checkout. The 30% Apple in-app purchase fee applies only to subscriptions that are processed through the iOS Patreon app at the moment of subscription. A patron who opens the Patreon page URL in a web browser — on any device, including an iPhone or iPad using mobile Safari — and subscribes through the browser does not trigger the in-app purchase fee. The subscription is processed through Stripe or another web payment processor at standard web transaction rates, not through Apple’s IAP system. After subscribing through the browser, the patron can use the Patreon iOS app to read posts, download files, and access all content without any fee consequence. The 30% commission applies only at the moment of subscription through the app checkout — not at content access time, not at renewal time if the subscription was originally established through the web.

For finger loop braiding creators, the practical action to protect creator income has two components. First, add a note to the Patreon page that is specific and dollar-denominated: “If you join through the Patreon app on your iPhone or iPad, Apple takes 30% of your pledge — that’s $1.50 from a $5 pledge and $3 from a $10 pledge — before I receive anything. Joining through a browser (tap the link, Safari will open) sends the full amount to me.” Second, for existing iOS-subscribed patrons, send a direct communication in September 2026 specifying the individual patron’s subscription amount and the exact monthly dollar amount that will go to Apple starting November 1: “Starting November 1, Apple will take $X.XX of your monthly pledge before it reaches me — that’s money that currently funds [specific pattern archive / specific documentation project]. Subscribing through a browser avoids this entirely. Here’s the direct link: [Patreon page URL].” The September timing gives monthly subscriptions renewing in October enough lead time to cancel iOS subscriptions and re-subscribe via browser before the November 1 cutover.

For the finger loop braiding audience specifically, the web-browser subscription path is particularly natural. Historical and SCA patrons frequently use Pinterest for visual reference research, following board links through mobile browser sessions to reach blog posts, documentation archives, and Patreon pages. The discovery journey for a Tudor reenactor looking for accurate loop braiding patterns typically goes: Pinterest pin showing a period garment or braid › blog post or Patreon preview › subscription page. That entire journey is browser-based from the start — the patron is already in a browser when they reach the subscription page. The Patreon note primarily serves to prevent the patron from switching to the Patreon app to complete the subscription after finding the page through a browser link, which is the specific behavior pattern that triggers the Apple IAP fee. Making the note visible and specific on the subscription page interrupts that switch before it happens.

KeepTier provides a hosted web-only checkout page at a creator’s own domain that handles this routing transparently: there is no iOS app involved in the checkout path at any point, the Stripe Checkout integration processes all subscriptions through the web by default, and the page can include messaging that explains the iOS fee situation to any patron arriving from any discovery channel. For finger loop braiding creators whose patron base is concentrated among historical reenactors, SCA members, and Tudor textile researchers who arrive primarily through Pinterest and browser-based reference research, a domain-hosted checkout page fits naturally into the existing discovery and subscription flow. The November 1, 2026 deadline is public and fixed.
