| Know before using | 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. | The record does not supply universal POM values, validate fit across a population, prove process capability, choose a statistical study or sampling plan, reproduce licensed standards, or replace qualified technical, fit, quality, statistical, safety, compliance, and legal review. | 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. | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. |

| What the source establishes | 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 guide cites current ISO, AATCC, and NIST sources for body and garment measurement boundaries, textile conditioning, dimensional-change testing, repeatability and reproducibility, and AQL-indexed sampling, while requiring the live product owner to set rather than inherit numerical tolerances. | 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. | The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. |
