| 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. | Partner status is not a blanket product claim; use the current official list and confirm the exact facility, material, process, or chemical-input scope. | The company count is a changing platform claim. Search fields, profiles, certificates, locations, and account access do not independently verify the legal entity, factory ownership, capability, capacity, certificate validity or scope, compliance performance, delivery, or project fit. Confirm the site and subcontracting, credentials with issuers, samples, audits when appropriate, specifications, contracts, and commercial terms. | 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. |

| 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. | bluesign publishes current system-partner lists and approved-input references that can support facility, material, chemical, dyeing, and finishing checks. | FOURSOURCE's current public network page presents an operator-reported global company count and country or territory search. It says logged-in users can narrow results by compliance certificates, product groups, fabric types, target groups, minimum order quantities, and other fields, with a free-trial and supplier sign-up route. | 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. |
