# Stitch Authority resource comparison Generated: 2026-07-23T14:39:11.363Z 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. FOURSOURCE Supplier Network Permanent record: Source page: - Primary job: Source production - Area: Production - For: Apparel brands - Location or jurisdiction: Global - Access: Free account - Format: Marketplace - Source type: Commercial marketplace - Linked page reviewed: 2026-07-21 - Next review due: 2027-01-17 ### Best for Searching global apparel and textile production capabilities ### What the source establishes FOURSOURCE's current public network page presents an operator-reported global company count and country or territory search. It says logged-in users can narrow results by compliance certificates, product groups, fabric types, target groups, minimum order quantities, and other fields, with a free-trial and supplier sign-up route. ### Know before using The company count is a changing platform claim. Search fields, profiles, certificates, locations, and account access do not independently verify the legal entity, factory ownership, capability, capacity, certificate validity or scope, compliance performance, delivery, or project fit. Confirm the site and subcontracting, credentials with issuers, samples, audits when appropriate, specifications, contracts, and commercial terms. ## 2. Optitex 2D/3D Pattern Design Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - 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 Integrated pattern, marker, and 3D production workflows ### What the source establishes Optitex's current page describes 2D pattern creation, grading, verification, Tech Pack Essentials, marker creation and nesting, cut and plot output, 3D virtual samples, fabric simulation, colour and print placement, tension maps, and avatar editing. Its support page lists native and standard CAD interchange routes and states that Optitex does not support macOS. ### Know before using Pricing is not public, modules and system requirements must be confirmed, and macOS is not supported. Vendor accuracy and fit language does not prove results for an actual product. Pilot native and exchanged files with the receiving supplier, calibrated materials, approved blocks and grade rules, marker and output devices, tech-pack fields, training, version control, and risk-appropriate physical fit and production checks. ## 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. ## 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.
