It is not a recommendation, provider approval, compliance decision, or record of project-specific due diligence. ## 1. 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. ## 2. GOTS Certified Suppliers Permanent record: Source page: - Primary job: Check standards - Area: Materials - For: Apparel brands - Location or jurisdiction: Global - Access: Open access - Format: Directory - Source type: Official registry - Linked page reviewed: 2026-07-15 - Next review due: 2026-10-13 ### Best for Checking GOTS certification records ### What the source establishes The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. ### Know before using A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. ## 3. 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. ## 4. NMSU Pattern Alteration Guide Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Makers - Location or jurisdiction: United States ยท North America - Access: Open access - Format: Reference - Source type: Government guidance - Linked page reviewed: 2026-07-21 - Next review due: 2026-10-19 ### Best for Checking a common flat-pattern alteration method ### What the source establishes New Mexico State University's current Cooperative Extension Guide C-228 explains three alteration methods, folding out fullness, slashing and spreading or overlapping, and redrawing darts or seams. It provides illustrated bodice, sleeve, skirt, and trouser examples and tells readers to compare body measurements plus intended ease with the pattern while preserving grain, design lines, related-piece changes, and comfort ease. ### Know before using The guide's general womenswear diagrams and ease ranges are teaching examples, not an individual diagnosis, current commercial-pattern specification, or complete fitting course. A named symptom can have several causes, and alterations may affect adjoining seams, facings, collars, sleeves, balance, and style. Verify the method against the exact pattern and test the coordinated changes on a muslin. ## 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.
