It is not a recommendation, provider approval, compliance decision, or record of project-specific due diligence. ## 1. Controlled Tech Pack Orientation Permanent record: Source page: - Primary job: Source production - Area: Production - 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 Understanding what a tech pack must control before using a template or releasing work ### What the source establishes The guide cites current ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it explicitly separates those authorities from product-specific technical and market decisions. ### Know before using An orientation rather than a completed product record; it does not supply a universal format, licensed standard content, measurements, tolerances, construction settings, labels, approvals, compliance conclusion, or product-release authority. ## 2. Yarn Database EU Dyers and Makers Permanent record: Source page: - Primary job: Choose materials - Area: Yarn - For: Makers - Location or jurisdiction: European Union - Access: Open access - Format: Directory - Source type: Community database - Linked page reviewed: 2026-07-15 - Next review due: 2027-01-11 ### Best for Finding independent EU yarn or fibre dyers with off-Ravelry purchase routes ### What the source establishes 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. ### Know before using 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. ## 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. Remove any route whose audience, jurisdiction, access, or scope does not match the job. 2. Open the permanent record and source page for every remaining route. 3. Recheck facts that can change after the listed review date. 4. Verify project-specific capability, terms, test evidence, and legal requirements with the responsible source or provider. 5. Record the reason for the final choice outside Stitch Authority.
