Know before usingThe directory is opt-in and excludes qualified people who do not list; designation does not guarantee availability, price, or suitability for a specific object or treatment.It is one curator's intentionally selective, off-Ravelry-oriented database, inventories change, and paid supporters can receive rotating priority placement; verify availability, fibre claims, shipping, and terms directly.The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review.Supplier content, uploaded certificates, and AI suggestions are leads, not independent verification. Public brand pricing and full access are not stated on the main page. Verify material identity and performance, certificate issuer and validity, supplier capability, samples, price, availability, commercial terms, data permissions, and any AI output before a sourcing decision.

Source and review
What the source establishesAIC says listed Professional Members complete a peer-reviewed application and may be searched by specialty, material, service, location, or name.The individually researched database offers free listings and sortable yarn, fibre, designer, editor, accessory, and location views; the EU page spans multiple countries and direct seller profiles.The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments.Material Exchange's current terms describe a business-to-business sourcing hub that connects brands and suppliers for AI-assisted material discovery, sample requests, bulk inquiries, negotiation, and collaboration. Suppliers upload product descriptions, availability, pricing, and certificates. The terms state that the platform cannot verify certificate accuracy and that AI results may be imperfect.
