| Know before using | The record does not provide universal fabric-weight classes, garment recommendations, test values, targets, tolerances, sampling counts, lot acceptance, drape or performance conclusions, compliance, or a substitute for representative swatches, product trials, and qualified textile, testing, product, quality, safety, sourcing, and compliance review. | 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 guide cites current ASTM and ISO sources for fabric mass per unit area, woven-fabric mass, sampling, conditioning, stiffness, and thickness plus the NIST conversion table; it separates method-defined measurements from product-defined targets, tolerances, and suitability. | 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. |
