Kogin-zashi is a Japanese counted textile embroidery technique from the Tsugaru region of Aomori Prefecture in northern Japan. It is distinct from the broader sashiko tradition — where regular running stitches form geometric patterns across the full cloth surface — in both its counting mechanics and its historical context: kogin-zashi is worked on the warp threads only (the needle passes over odd numbers of warp threads and under even numbers, building a relief pattern on the cloth surface), uses white cotton thread on indigo-dyed cloth (producing the characteristic indigo-ground white-pattern visual vocabulary), and developed historically as a technique for reinforcing and insulating the humble hemp and cotton work garments of Tsugaru farmers and craft workers during harsh northern winters. For Patreon creators, kogin-zashi occupies a niche at the intersection of Japanese craft heritage, counted thread technique instruction, and the slow-craft and maker movements — an audience with a strong online presence, high iOS device penetration, and an appreciation for regional Japanese craft traditions that drives premium subscription willingness.

The modoro stitch: counting over warp threads

The kogin-zashi stitch — called modoro in Japanese, from the verb modoru (to return) — has a specific counting mechanic that sets it apart from both regular sashiko running stitch and from Western counted thread techniques like cross-stitch or needlepoint. The needle passes over an odd number of warp threads (1, 3, 5, 7, or 9 warp threads) and under an even number (2 warp threads at minimum, typically 2 consistently), working horizontally across the cloth. The critical rule: the needle always passes over an odd number and under an even number — this odd-over rule creates the characteristic visual relief of the technique, where the floating thread across multiple warp threads catches light and reads as a distinct textural surface. Counting error in kogin-zashi is immediately visible in the finished row because the pattern unit breaks — the geometric symmetry of each motif depends on consistent odd-over counting, and a single count error propagates visually across the entire motif. This counting precision is the primary instructional content for kogin-zashi Patreon creators: specific pattern charts with row-by-row count documentation, the identification and correction of common counting errors, and the technique for verifying count accuracy before committing a full row to the cloth.

Row structure: each row is worked horizontally across the cloth from right to left (the conventional Japanese working direction) or left to right (for left-handed workers), with each horizontal row building the next layer of the geometric pattern. Between rows, the needle turns at the edge of the working area and returns in the opposite direction on the next row directly above. Weft threads — the horizontal threads of the cloth — are never used in the counting: the needle travels between weft threads but counts only warp threads (the vertical structural threads). This warp-only counting is what creates the directional texture of kogin-zashi: the white thread floats only horizontally across the indigo cloth, building a completely horizontal-orientation pattern regardless of the diagonal or diagonal-ish visual form of the pattern motifs themselves.

Pattern units: construction and symmetry

Kogin-zashi patterns are built from modular units called motifs or pattern units, each defined by a specific sequence of stitch count values (the number of warp threads passed over at each stitch position) across a defined number of rows. The most common traditional kogin pattern unit is the kiku (chrysanthemum) form: a diamond-shaped central element with radiating stitch extensions, built over 9–15 rows and approximately 25–45 warp threads wide, constructed by starting with a maximum count stitch (e.g., 9 warp threads over) at the center row and decreasing by 2 count on each successive row above and below (7, 5, 3, 1), then increasing back to 9 for the second half of the diamond. The count sequence defines the shape precisely: a correctly counted kiku unit has perfect bilateral symmetry on all four axes, and any count deviation produces a visually asymmetrical unit that identifies the error row immediately on inspection. Pattern units are joined by repeating the unit across the horizontal cloth width with consistent inter-unit spacing; traditionally the units are placed with zero gap (edge-sharing) or 1–2 warp threads between units for visual rhythm. Vertical stacking of pattern units creates the finished cloth surface — typically 8–15 identical rows of repeated units to fill a garment panel.

Katako and kofukin: the historical cloth types

Two primary historical kogin-zashi cloth forms provide the framework for modern pattern documentation. Katako (shoulder cloth or jacket): the work jacket worn by farmers and craftworkers in the Tsugaru region, reinforced with kogin-zashi patterns across the shoulders, chest, and sleeves — the areas subject to greatest wear and tear. Katako kogin patterns are typically bold, high-count motifs that provide maximum thread coverage and therefore maximum insulating reinforcement: the tradition understood the double function of the embroidery as both decorative identity marker and practical fiber-density-increasing insulation layer. Katako patterns from the Aomori Prefectural Museum collection and the Hirosaki Folkloric Museum are the primary reference sources for traditional motif vocabulary. Kofukin (small cloth or tenugui-scale cloth): a smaller, more finely worked cloth used for ritual, gift-giving, or demonstration purposes rather than daily wear. Kofukin patterns tend to be more intricate and finer in thread count, demonstrating the maker's technical skill rather than maximizing insulation. The distinction between katako (functional) and kofukin (demonstration) kogin is the historical analogue of the contemporary Patreon creator's content decision about whether to teach large-scale wearable project patterns (katako orientation) or small-sample technique demonstration pieces (kofukin orientation).

Materials: cloth and thread selection

Authentic kogin-zashi uses indigo-dyed even-weave linen or cotton cloth with a clearly visible, regular warp structure. Contemporary kogin-zashi practitioners use: Zweigart Belfast 32-count linen in navy (for the closest equivalent to traditional indigo cloth at manageable thread count); Linen Japanblau from Fa. Kuhn in Germany (the specialist supplier most used in contemporary Japanese and German kogin practice); or hand-dyed linen indigo cloth at 28–35 count from specialist Japanese suppliers. The thread count of the fabric directly affects pattern scale: on 32-count cloth, a 9-over-warp-thread stitch spans approximately 4.5mm; on 28-count cloth, the same stitch spans approximately 5.1mm. Thread: traditionally white momen (cotton) thread; contemporary practitioners use DMC Retors Mat #4 (the matte cotton equivalent of pearl cotton), Anchor Pearl Cotton #5 and #8, or specialist kogin thread from Japanese suppliers (Olympus kogin thread, available in the original white as well as a modern expanded color palette). White is traditional and historically correct; using off-white or cream thread produces a softer visual contrast against navy cloth that some contemporary practitioners prefer for items not intended as historical reproductions.

Apple Tax on iOS Patreon subscriptions: what kogin-zashi creators lose from November 2026

Apple's 30% iOS IAP fee on Patreon subscriptions applies from November 1, 2026. Kogin-zashi creators reach their audience through Instagram (Japanese craft, textile art, and slow-stitch process photography, 74–85% iOS — the Japanese craft and textile Instagram audience is among the highest iOS-concentration craft demographics; the clean aesthetic of white-on-indigo kogin photography resonates strongly with iPhone-using design-aware audiences), Pinterest (Japanese craft and textile boards, 67–80% iOS), and YouTube (kogin-zashi technique tutorials, 55–68% iOS). Platform iOS average for the kogin-zashi audience: approximately 72–80% iOS weighted toward Instagram primary traffic.

Revenue lost per iOS subscriber from November 2026: at $100/month total Patreon revenue, 74% iOS: $100 × 0.74 × 0.30 = $22.20/month ($266.40/year). At $180/month, 77% iOS: $180 × 0.77 × 0.30 = $41.58/month ($498.96/year). At $280/month, 80% iOS: $280 × 0.80 × 0.30 = $67.20/month ($806.40/year). For a kogin-zashi creator in the $100–$200/month total revenue range typical for specialist Japanese craft Patreons, the Apple Tax extracts a structurally significant fraction of subscription income — effectively one to two patron-months of revenue annually per iOS subscriber.

KeepTier: web checkout that preserves creator revenue

KeepTier processes subscriptions through Stripe web checkout, operating outside Apple's iOS IAP system. When a patron subscribes via a KeepTier creator page link, the full subscription amount reaches the creator without Apple's 30% deduction. For a kogin-zashi creator at $180/month with 77% iOS exposure, routing new patron subscriptions to KeepTier preserves $41.58/month per iOS subscriber — $498.96 annually per patron — that would otherwise be transferred to Apple.
