Know before usingCommunity 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-reviewed describes the page and its cited decision boundaries. It does not authenticate a commercial roll, seller claim, fibre percentage, construction, finish, performance result, machine setting, care route, compliance status, supplier, or product fitness. Internal browse bands are navigation labels, not textile standards or product classes; an entry without a usable listed mass range is unclassified. Check the actual article, seller data, care label, equipment instructions, representative assemblies, applicable rules, and project requirements before deciding.An orientation rather than a completed product record; it does not supply a universal format, licensed standard content, measurements, tolerances, construction settings, labels, approvals, compliance conclusion, or product-release authority.A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Yarn records can be incomplete or wrong, prices and availability vary by market, and the site uses affiliate links. Confirm the required gauge, total length, fibre behavior, construction, care, color, dye lot, accessibility, and seller terms, then make and assess a representative swatch before committing.

Source and review
What the source establishesThreadloop'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.All 50 current cloth entries meet the source-reviewed content contract. The public index, cards, permanent pages, and site search expose that state, while the repository audit enforces a current review date, substantive scope, decision boundaries, and at least three external sources. The migrated cases cover fibre and family representations, woven and knitted construction, open nets, raised and dimensional surfaces, mass, thickness, drape, elasticity, colour, seams, pressing, care state, supports, and complete-product decisions.The guide cites current ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it explicitly separates those authorities from product-specific technical and market decisions.YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggested replacements, and each yarn page provides a route to report source-data problems.
