Know before usingThis 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.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.

Source and review
What the source establishesASDP'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 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.
