| Know before using | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. | This is Woolmark-operated education focused on wool, not a neutral comparison of all fibres or processing systems. A completion badge records coursework, not independent proof of production competence, product performance, environmental impact, or compliance. Confirm technical values and local requirements against current standards before production use. | 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. | 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. |

| What the source establishes | The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. | The current Woolmark Learning Centre library publishes free account-based coursework with module counts, completion times, progress tracking, knowledge checks, and supporting resources. Its wool programs cover fibre science, raw-wool and yarn processing, dyeing and finishing, woven textiles, knitwear, product quality, and wastewater management for learners and facilitators. | 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. | 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. |
