| Know before using | An account is required and community, publisher, designer, shop, yarn, and project records can vary in currency and accuracy. Search results, ratings, favorites, and project examples do not establish pattern accuracy, yarn availability, seller reliability, fit, gauge, or project suitability. Confirm current files, errata, license, purchase and refund terms, measurements, yarn details, and shop information with the responsible source. | 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. | 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. | Supplier content, uploaded certificates, and AI suggestions are leads, not independent verification. Public brand pricing and full access are not stated on the main page. Verify material identity and performance, certificate issuer and validity, supplier capability, samples, price, availability, commercial terms, data permissions, and any AI output before a sourcing decision. |

| What the source establishes | Ravelry's official description identifies a user-driven database of knitting and crochet patterns and yarns, searchable directories for designers, pattern sources, local yarn stores and yarn brands, and a personal notebook for projects, stash, tools, library items, queues, and favorites. Community members and volunteer editors add and maintain the database records. | 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. | 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. | Material Exchange's current terms describe a business-to-business sourcing hub that connects brands and suppliers for AI-assisted material discovery, sample requests, bulk inquiries, negotiation, and collaboration. Suppliers upload product descriptions, availability, pricing, and certificates. The terms state that the platform cannot verify certificate accuracy and that AI results may be imperfect. |
