| Know before using | This is a member referral directory, not a Stitch Authority roster or approval. 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, or referral availability does not establish credentials, experience, capacity, insurance, price, accessibility, workmanship, schedule, or project fit. Check those points, references, scope, samples, terms, and remedies 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. |

| What the source establishes | ASDP's public directory searches members currently accepting referrals by location and professional specialty, including patternmakers, production sewers, designers, teachers, tailors, alteration specialists, and fabric or materials suppliers. A result opens a member profile and a contact action, and the page identifies the population as association members in good standing. | 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. |
