| Know before using | The workflow is not a contract or quality certification; local legal duties and technical review may still apply. | 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. | 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. | Free access does not grant commercial reproduction or sale rights; uses beyond one personal copy must be resolved with the designer or author. Knitty says it tries to avoid errors but disclaims responsibility for pattern and technique inaccuracies. Check the live page for corrections, verify gauge and measurements, and confirm permission before any commercial use. |

| Source and review | ||||
| What the source establishes | The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. | 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. | 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. Current terms state that the free plan requires no card, paid upgrades start billing immediately, cancellation retains paid features through the current cycle, and the account then returns to free features. | Knitty currently publishes web-only editorial issues containing original knitting and crochet patterns and articles. Its legal page states that patterns are free for one person's personal use, identifies each designer or author as the copyright holder, and explains that verified pattern corrections are posted in bright pink on the pattern page. |
