# Stitch Authority resource comparison Generated: 2026-07-23T22:56:01.986Z Comparison: This file preserves the published decision metadata for the selected routes. It is not a recommendation, provider approval, compliance decision, or record of project-specific due diligence. ## 1. QuiltMap Permanent record: Source page: - Primary job: Choose materials - Area: Materials - For: Makers - Location or jurisdiction: Global - Access: Open access - Format: Directory - Source type: First-party platform - Linked page reviewed: 2026-07-15 - Next review due: 2027-01-11 ### Best for Finding quilt-material sellers and adjacent quilting services by country or map ### What the source establishes QuiltMap describes free public search and free basic listings, community submissions and claims, and country routes covering North America, Europe, Japan, South Korea, and Australia. ### Know before using Coverage is quilting-specific and uneven by country; businesses can pay for enhanced features, and community or owner updates do not verify inventory, service quality, hours, or availability. ## 2. Pattern Testers Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Apparel brands - Location or jurisdiction: Global - Access: Free + paid - Format: Software - Source type: First-party platform - Linked page reviewed: 2026-07-21 - Next review due: 2027-01-17 ### Best for Coordinating an independent sewing-pattern test ### What the source establishes Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed. ### Know before using The interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer. ## 3. YarnSub Permanent record: Source page: - Primary job: Choose materials - Area: Yarn - For: Makers - Location or jurisdiction: Global - Access: Open access - Format: Reference - Source type: First-party platform - Linked page reviewed: 2026-07-21 - Next review due: 2027-01-17 ### Best for Replacing a discontinued or unavailable yarn ### What the source establishes YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggested replacements, and each yarn page provides a route to report source-data problems. ### Know before using A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Yarn records can be incomplete or wrong, prices and availability vary by market, and the site uses affiliate links. Confirm the required gauge, total length, fibre behavior, construction, care, color, dye lot, accessibility, and seller terms, then make and assess a representative swatch before committing. ## 4. 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.
