Best forChecking which U.S. alias the current Craft Yarn Council table gives a known metric package size before confirming project gaugeResearching loom-ready weaving structures and draftsCoordinating an independent sewing-pattern testSearching current and out-of-print sewing patterns
Know before usingThe reference is not a dimensional measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, gauge result, or proof that a proposed tool will produce the required fabric.A visible drawdown is not automatically a complete, corrected, rights-cleared, or loom-compatible project plan. Full draft data and advanced tools require a renewing subscription, and historical sources can contain errors or unclear provenance. Check shafts, treadles, tie-up, sett, yarn, floats, repeats, copyright status, and WIF compatibility before committing a warp.The interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer.Community members add and quality-control the records, so confirm sizing, measurements, fabric suggestions, format, availability, errata, license, and purchase terms with the designer or publisher. Adding an entry to a stash does not provide the pattern files. Saved searches and private PDF storage are paid Plus features, and a listing or review does not establish pattern accuracy or fit.

Source and review
What the source establishesThe lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows and follows the Council's warning that company letter and number labels vary; blank aliases remain blank instead of being inferred.Handweaving.net currently exposes the Ralph Griswold digital archive, document downloads, draft drawdown views, basic-account clipboards, and video tutorials without a paid subscription. Its subscription page reserves full drafts, WIF downloads, draft creation and editing, color tools, profile and block substitution, arrangement, repeats, and related browser tools for subscribers.Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed.Threadloop's official guide describes an independent, fully crowdsourced database covering available and out-of-print sewing patterns. Its search supports pattern type, fabric type, age group, body type, cup size, level, format, file features, language, measurements, availability, and other filters; members can also track a stash, wishlist, projects, reviews, and discussions.
