| 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. | A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Records can be incomplete or wrong, price bands are approximate, availability varies by country and seller, and shade-level matching is unavailable. YarnSub says affiliate status does not change suggestions, but equally rated matches are ordered by brand popularity. Confirm required gauge, total length, fibre behavior, construction, care, colour, dye lot, accessibility, price, availability, and seller terms, then make and assess a representative swatch before committing. | The record does not reproduce licensed code diagrams, verify a user's proposed code, authorize an ISO and ASTM crosswalk, select a construction, set stitch density or machine settings, prove supplier repeatability or performance, or replace the licensed standards and qualified construction, sewing, production, testing, safety, and quality review. |

| Source and review | ||||
| 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. Current terms state that the free plan requires no card, paid upgrades start billing immediately, cancellation retains paid features through the current cycle, and the account then returns to free features. | YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggestions. Result filters can exclude animal, animal-derived, synthetic, or plant fibre groups and use a subjective $ to $$$$$ price indicator. The site does not accept user-entered yarn details, individual shade cards, or expose an API. Each yarn page provides a data-issue route. | The guide cites the official DLA cancellation record for FED-STD-751A and the current public scopes and statuses of ISO 4915:1991, ISO 4916:1991, and ASTM D6193-16(2025). It records ISO 4915's July 2026 systematic review and keeps classification, ambiguous-code recovery, translation, complete process definition, physical verification, and performance evidence separate. |
