| Know before using | This is a member referral directory, not a Stitch Authority roster or approval. The observed result count can change and is not a practitioner census. ASDP states that it makes no representations, warranties, or guarantees and assumes no responsibility for members' products or services. Membership, a code of ethics, a profile, a patternmaking category, or stated referral availability does not establish identity, credentials, experience, current availability, capacity, insurance, price, accessibility, workmanship, file compatibility, schedule, or project fit. Confirm those points, references, scope, samples, terms, and remedies directly. | This is Woolmark-operated education focused on wool, not a neutral comparison of all fibres or processing systems. A completion badge records coursework, not independent proof of production competence, product performance, environmental impact, or compliance. Confirm technical values and local requirements against current standards before production use. | 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. |

| What the source establishes | ASDP's public directory searches members currently accepting referrals by location and professional specialty. At the July 26, 2026 check, its Patternmaking & Related Services filter returned 15 opted-in profiles with specialties, service-location text, profile or contact routes, and some remote-service notes. The page identifies the population as association members in good standing. | The current Woolmark Learning Centre library publishes free account-based coursework with module counts, completion times, progress tracking, knowledge checks, and supporting resources. Its wool programs cover fibre science, raw-wool and yarn processing, dyeing and finishing, woven textiles, knitwear, product quality, and wastewater management for learners and facilitators. | 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. |
