Know before usingIt contains association members rather than the whole market; membership does not establish capacity, pricing, workmanship, certification, labor conditions, or project fit.An orientation rather than a completed product record; it does not supply a universal format, licensed standard content, measurements, tolerances, construction settings, labels, approvals, compliance conclusion, or product-release authority.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.A foundational library, not yet an exhaustive stitch encyclopedia.

Source and review
What the source establishesAAPN states that its public directory can be searched by company, country, or category and spans factories, textiles, trim, logistics, services, and technology.The guide cites current ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it explicitly separates those authorities from product-specific technical and market decisions.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 linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface.
