# Stitch Authority resource comparison Generated: 2026-07-23T17:03:01.751Z 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. 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. 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. ## 3. Material Exchange Permanent record: Source page: - Primary job: Choose materials - Area: Materials - For: Apparel brands - Location or jurisdiction: Global - Access: Quote-based - Format: Software - Source type: First-party platform - Linked page reviewed: 2026-07-21 - Next review due: 2027-01-17 ### Best for Structured material sourcing across teams ### What the source establishes Material Exchange's current terms describe a business-to-business sourcing hub that connects brands and suppliers for AI-assisted material discovery, sample requests, bulk inquiries, negotiation, and collaboration. Suppliers upload product descriptions, availability, pricing, and certificates. The terms state that the platform cannot verify certificate accuracy and that AI results may be imperfect. ### Know before using Supplier content, uploaded certificates, and AI suggestions are leads, not independent verification. Public brand pricing and full access are not stated on the main page. Verify material identity and performance, certificate issuer and validity, supplier capability, samples, price, availability, commercial terms, data permissions, and any AI output before a sourcing decision. ## 4. 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. ## 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.
