| Know before using | These are voluntary industry guidelines, not law, a licensed test method, or proof that a yarn, hook, needle, pattern, size, or care instruction suits a project. Publishers, manufacturers, and regions may use different names, aliases, chart symbols, size tables, and weight systems. Confirm the actual pattern key, measured tool diameter, yarn label and specifications, body or garment measurements, gauge, care evidence, and destination-market requirements. | 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. | 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. |

| What the source establishes | The Craft Yarn Council's current gateway publishes its yarn-weight system, crochet and knitting chart symbols and abbreviations, project levels, body-size tables, hook and needle aliases, care symbols, designer guidance, downloadable symbols, and a guideline PDF. The Council says yarn companies, tool manufacturers, publishers, and consultants developed the guidance to improve consistency in labels and patterns and asks industry participants to adopt it. | 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. | 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. |
