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.AFIRM states that its list is guidance, not legal advice, an industry standard of care, or a guarantee of completeness or brand acceptance. It does not replace current law, a customer's stricter RSL, manufacturing-input controls, a product-specific risk and sampling plan, accepted laboratory methods, supplier controls, or performance and safety testing.It is a translation and orientation layer, not legal advice, certification approval, a purchased standard, or proof that a supplier, sample, or lot conforms.

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.AFIRM publishes a 2026 multilingual Restricted Substances List for chemicals in finished apparel, footwear, accessories, and related materials, with a material-specific testing matrix. Its FAQ says the list does not cover product-performance testing, distinguishes the finished-product RSL from manufacturing-input lists, and tells suppliers to check each customer's brand-specific requirements and testing acceptance.Each entry includes plain-language aliases, a working definition, a decision boundary, a checked source, and an internal next step; a repository audit enforces completeness and review dates.
