| Know before using | ATA's completeness language is an operator claim. Buyer-guide or member-directory inclusion does not establish a complete market map, current production capability, capacity, ownership, certification, product suitability, commercial terms, or project fit. Verify the actual company, site, product, documents, samples, and terms directly. | 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 result is a numerical unit conversion, not a new measurement or conformance decision; it does not establish sample or lot representativeness, significant digits, drape, warmth, opacity, thickness, stretch, strength, shrinkage, durability, sewability, end use, target, or tolerance. |

| What the source establishes | ATA's current sourcing page links buyer's guides covering suppliers and products, a searchable member directory, and other association sourcing tools for the advanced and specialty-textile supply chain. ATA's own directory overview describes company listings and product showcases as ways for fabricators to find products and potential partners. | 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 calculator uses the NIST SP 811 Appendix B.8 conversion from avoirdupois ounces per square yard to kilograms per square metre and links to a source-reviewed fabric mass record for method, sampling, conditioning, and product controls. |
