ShaftDraft Weaver

ShaftDraft Weaver is an offline-first handweaving draft studio for guild weavers, textile students, rigid-heddle weavers moving up to multi-shaft looms, and loom-room apprentices. Design and verify drafts before you wind a warp—so you waste less yarn and teach structure with confidence. LIVE DRAFT WORKBENCH Lock shaft count (4–16) and treadle count, paint threading across ends on a zoomable grid, toggle the tie-up matrix cell by cell, and enter treadling rows. The fabric drawdown updates on every edit so you see structure, not guesswork. STRUCTURE READOUT YOU CAN TRUST Get plain-language labels for common families—plain, twills, satins, basket, and Bronson-style patterns—plus float-length warnings and warp/weft dominance hints before cloth is on the loom. SEEDED LIBRARY, PRIVATE LOCAL SAVES Open classic drafts in one tap: plain weave, 2/2 twill, broken twill, herringbone, bird’s-eye, 5-end satin, basket, and teaching samples with short coach notes. Save named drafts on-device only—duplicate, rename, archive, and reopen anytime. No accounts. No cloud sync. SETT & EPI COMPANION Enter wraps-per-inch or preferred sett, fabric width, and loom waste factors to estimate ends, warp length, and approximate yardage before you measure yarn. TECHNIQUE GUIDE BUILT FOR LEARNING Short screens on shaft anatomy, reading a draft, tie-up conventions, and balancing floats, plus a mini quiz that unlocks glossary callouts—instructional depth, not a bare calculator or scrapbook. EXPORT FOR CLASS AND GUILD Preview a full-screen drawdown and print-style draft sheet with warp color stripes and weft row tinting. Share a PNG via the system share sheet only when you choose; files leave the device solely on explicit share. PRIVACY BY DESIGN Offline-only storage, no ads or analytics SDKs, first-run onboarding, and always-reachable Privacy Policy and Terms. Built for focused studio work with a clear Material workbench across Library, Workbench, Sett, Guide, and Settings. Whether you are drafting for a guild sample exchange, a class handout, or your next multi-shaft project, ShaftDraft Weaver helps you lock the structure first—then wind the warp.
