Know before usingThe reference is not a dimensional measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, gauge result, or proof that a proposed tool will produce the required fabric.Public pages explain the organization and calendar, while many classes, meetings, programs, and benefits require registration, payment, or membership. CGOA's statement that it sets a national standard is its own mission language, not evidence that every class, member, chapter, instructor, or portfolio is independently accredited, approved, or suitable for a particular learner.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.

Source and review
What the source establishesThe lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows and follows the Council's warning that company letter and number labels vary; blank aliases remain blank instead of being inferred.CGOA's current public pages identify it as a volunteer-led nonprofit and describe online education, in-person and online events, local chapters, mentorship, scholarships, professional programming, and portfolio-based Masters skill-building programs. Its calendar distinguishes specific classes, meetings, retreats, and professional events.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.
