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.AAFA provides the list for information only and says it is voluntary, may contain omissions or inaccuracies, and is not legal advice. A global most-restrictive value is not a complete market or product determination. Verify the current controlling law, jurisdiction, product and component scope, exemptions, effective dates, test method, sampling plan, brand requirements, manufacturing-input controls, and other safety rules.The workflow is not a contract or quality certification; local legal duties and technical review may still apply.

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.AAFA published RSL Version 26 on January 28, 2026 in searchable spreadsheet and PDF formats. The association describes it as a regularly updated reference to laws and regulations restricting chemicals in finished apparel, footwear, accessories, and home textiles. Its methodology records final-product or component limits, jurisdiction, test method, and comments, and excludes factory-process restrictions and non-chemical product-safety rules.The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface.
