Source and review
What the source establishesThreadloop'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.AIC says listed Professional Members complete a peer-reviewed application and may be searched by specialty, material, service, location, or name.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.
