How does brioche stitch work mechanically, and what is the brk, brp, and yosl system?

Brioche knitting is a held-stitch architecture: every stitch in brioche is worked together with a yarn over that was accumulated on it during the previous row. The result is a fabric with twice the number of yarn-overs as a standard ribbed fabric, producing the characteristic deep, squishy honeycomb texture with twice the thickness and twice the stretch of ordinary k1p1 rib. The notation system established by Nancy Marchant in The Brioche Knitting Book defines three actions: brk (brioche knit), brp (brioche purl), and yosl (yarn over, slip one). On the setup row (or in the setup portion of a round), every stitch that will be a brioche purl on the next row is worked as yosl: bring the yarn to the front, slip the next stitch purlwise, then move on — the yarn over sits on the slipped stitch waiting for the next row. On the working row, the brk stitch is worked by inserting the needle into the stitch one row below (the same stitch that was slipped, but the stitch from the row before that), inserting through both the stitch below and the yarn over that was accumulated on it, and knitting both together. This is the 'stitch below' insert: the needle goes into the body of the fabric one round below the current needle level. The brp stitch purls the current stitch together with its yarn over in a similar combined action. The key mechanical point: in brioche, the stitches on the needle always alternate between live stitches and slipped stitches-with-yarn-overs. After each brioche row, the yarn-over-slipped stitches waiting to be worked next row are always in the same positions. This alternating stitch architecture means that a brioche knitter is always working only half the stitches in each row — the other half are slipped and waiting. This is why brioche grows half as fast as standard stockinette for the same number of rows. For Patreon creators, explaining this held-stitch architecture — and demonstrating the stitch-below insert from multiple camera angles — is the critical technical module that unlocks brioche for learners who have previously found the notation confusing.

How does two-color brioche work and what is yarn dominance?

Two-color brioche (2CBrioche) is worked in alternating rounds or rows, each color appearing every other round. The two colors are designated A and B. Round structure: Round A works all brk and brp stitches in color A, slipping the B-color stitches with yarn overs. Round B works all brk and brp stitches in color B, slipping the A-color stitches with yarn overs. After two rounds (one round of each color), the fabric has grown by one visible row of brioche texture. The face of the fabric shows one color in the raised ribs and one color in the recessed ribs — the color assignment depends on which color is in the knit position and which in the purl position for each stitch. When working in the round, the two yarns alternate at the beginning of each round. When working flat (back and forth rows), the two colors alternate at the beginning of each row, with the unused color simply dropped and picked up at the row start. Yarn dominance: in two-color brioche, the two colors appear at different apparent depths in the fabric. The dominant color (the color held in the left hand, or the color that loops around from below in the working direction) appears slightly more prominent — the stitches worked in the dominant color pull slightly deeper into the fabric, increasing the apparent contrast. Changing which color is dominant shifts the visual depth of the entire color pattern. A brioche swatch worked with color A dominant and then rewashed and reblocked with color A non-dominant shows noticeably different visual weight even though the stitch structure is identical. For Patreon creators teaching two-color brioche, demonstrating yarn dominance with a direct swatch comparison — same pattern, two swatches, dominance swapped — is one of the most valuable intermediate-tier instructional contributions.

How should brioche knitting creators structure Patreon tiers and what is the Apple Tax impact?

Brioche knitting Patreon tiers should reflect the technique's progression from one-color held-stitch foundation through two-color alternating-round structure to advanced shaping and design system work. Tier 1 — Stitch Below ($12–15/month): monthly pattern for a one-color brioche project — a cowl, hat, or headband in standard brioche rib — with full stitch count, cast-on specification (Italian cast-on instructions included), and blocking notes. The Italian cast-on sets up alternating knit-purl leg positions from the first row without requiring a separate ribbing cast-on, and is the correct cast-on for brioche; demonstrating it in the pattern PDF rather than assuming the subscriber knows it reduces beginner errors significantly. Tier 2 — Two Colors ($28–35/month): monthly pattern plus video demonstrating the two-color brioche setup — winding both colors, joining the second color, the round-by-round alternation, managing the yarn carry at round start, and a dominance demonstration swatch comparison. The video should also cover the most common two-color brioche error: working both stitches of a pair in the same color instead of alternating, which produces an incorrectly structured round. Tier 3 — Pattern Design ($50–65/month): monthly pattern plus video plus a design module covering brioche shaping (adding brioche increases and decreases, which require specific paired actions to maintain the stitch architecture), brioche colorwork (working color patterning within the two-color brioche round structure), or two-color brioche in the round vs flat (the working differences and how flat brioche avoids the common mistake of forgetting to alternate at the row turn). Apple Tax impact at $28/month with 72% iOS reach (brioche knitting audiences on Instagram and YouTube run 68–76% iOS) and 55 subscribers: $28 × 0.72 × 0.30 = $6.05 per subscriber/month × 55 = $332.64/month ($3,991.68/year) permanently lost to Apple IAP after November 2026. Web checkout via KeepTier captures this loss on new subscriptions routed through YouTube descriptions, Instagram bio, or blog subscription links.

Patreon for brioche knitting creators: brk brp yosl held-stitch architecture, two-color brioche alternating rounds, yarn dominance, Italian cast-on, Nancy Marchant notation, and Apple Tax impact in 2026

2026-07-30 · KeepTier

Brioche knitting is a held-stitch technique that produces a deep, reversible, honeycomb-textured fabric by always knitting or purling each stitch together with a yarn over accumulated from the previous row. The notation — brk (brioche knit), brp (brioche purl), yosl (yarn over, slip one) — was established by designer Nancy Marchant and forms the consistent vocabulary used in contemporary brioche patterns. Two-color brioche, worked in alternating rounds, extends this into striking color contrast with each color face showing on a different side of the fabric. For Patreon creators, the combination of complex visual result, unintuitive stitch mechanics, and significant video instructional value makes brioche knitting a strong subscription niche.

The held-stitch architecture of brioche

In standard ribbing, knit and purl stitches alternate and each stitch is worked independently. In brioche, every stitch that will be knit on the next row is first set up as a yosl (yarn over, slip one purlwise with yarn in front) on the current row — accumulating a yarn over on the slipped stitch so that the next row’s brk works both the stitch and its yarn over together. The brk insert goes one row below the needle, into the body of the slipped stitch from the previous row, capturing both the old stitch and its accumulated yarn over and knitting them together. This “stitch below” insert — the needle going into the fabric below the level of the current needle — is the kinesthetic signature of brioche knitting and the moment most clearly requiring video instruction to learn from observation.

Two-color brioche and yarn dominance

In two-color brioche, each color works every other round, building up alternating columns of each color on each face of the fabric. The visual depth of each color — which color appears more raised — is determined by yarn dominance: the color held in the dominant position (below, in English-style knitting) loops slightly deeper into each stitch and appears more prominent. Demonstrating dominance with a direct swatch comparison is the most impactful intermediate teaching moment for a brioche Patreon creator.

Cast-on and tier structure

The Italian cast-on (alternating half-hitch cast-on) sets up alternating knit and purl legs from the first cast-on stitch, which is the correct starting configuration for brioche. A standard long-tail cast-on requires a setup row before brioche can begin. Brioche Patreon tiers should mirror the skill progression: one-color brioche at tier one ($12–15/month), two-color brioche with video at tier two ($28–35/month), and design and shaping systems at tier three ($50–65/month).
