It is not a recommendation, provider approval, compliance decision, or record of project-specific due diligence. ## 1. Threadloop Sewing Pattern Database Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Makers - Location or jurisdiction: Global - Access: Free account - Format: Community - Source type: Community database - Linked page reviewed: 2026-07-21 - Next review due: 2027-01-17 ### Best for Searching current and out-of-print sewing patterns ### What the source establishes 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. ### Know before using 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. ## 2. Handweavers Guild of America Resources Permanent record: Source page: - Primary job: Learn techniques - Area: Techniques & repair - For: Makers - Location or jurisdiction: Global - Access: Open access - Format: Directory - Source type: Industry organization - Linked page reviewed: 2026-07-21 - Next review due: 2027-01-17 ### Best for Finding a weaving, spinning, or dyeing community ### What the source establishes The Handweavers Guild of America's current resources page links a searchable affiliate-guild directory, a paid professional-member directory and fiber-art resource guide, book reviews, a public event calendar, scholarships, a quarterly member magazine, and program and store information for weaving, spinning, dyeing, and related fiber arts. ### Know before using Coverage reflects affiliated guilds, submitted events, and participating professionals rather than every regional option. HGA states that its paid professional listings are supplied and updated by the professional and are not HGA endorsements. Confirm current contact details, teaching format, accessibility, price, skill level, and safeguarding or insurance needs directly. ## 3. Apparel Grade-Rule & Size-Run Validation Record Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Apparel brands - Location or jurisdiction: Global - Access: Open access - Format: Stitch Authority - Source type: Stitch Authority - Linked page reviewed: 2026-07-16 - Next review due: 2027-07-16 ### Best for Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence ### What the source establishes 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. ### Know before using 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. ## Next checks 1.
