# Stitch Authority resource comparison Generated: 2026-07-28T16:41:01.099Z 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. ZDHC Manufacturing Restricted Substances List Permanent record: Source page: - Primary job: Check standards - Area: Standards - For: Apparel brands - Location or jurisdiction: Global - Access: Open access - Format: Reference - Source type: Industry organization - Linked page reviewed: 2026-07-21 - Next review due: 2026-10-19 ### Best for Chemical-input controls during manufacturing ### What the source establishes ZDHC's current scope defines the MRSL as restrictions on intentional use of listed substances in commercial chemical formulations for textile, leather, rubber, foam, adhesive, and trim processing. Covered inputs include cleaners, dyes, auxiliaries, coatings, finishing agents, maintenance, wastewater-treatment, sanitation, and pest-control chemicals. ZDHC's help centre identifies version 3.1 as the current official MRSL and distinguishes it from restrictions measured in finished products. ### Know before using The MRSL controls manufacturing inputs within its stated scope. It does not by itself prove a facility's chemical inventory, implementation, worker protection, emissions, wastewater performance, formulation conformance, or finished-product compliance. Verify the current version, law, brand program, safety rules, chemical-product certificates and status, facility records, and finished-product RSL and testing requirements. ## 2. Yarnpond Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Both - Location or jurisdiction: Global - Access: Free + paid - Format: Community - Source type: First-party platform - Linked page reviewed: 2026-07-28 - Next review due: 2027-01-24 ### Best for Running knit or crochet pattern tests ### What the source establishes Yarnpond's current pages let knit and crochet designers publish public or private testing calls, select applicants, communicate with test teams, set milestones, collect feedback, post sample-making calls, and advertise tech-editing jobs. Testers can participate without charge, while designers pay per testing or job post, use credits that the pricing page says do not expire, or use a monthly subscription that the page says can be canceled. ### Know before using The platform is for knit and crochet rather than sewing, and a profile, application, rating, or platform listing does not prove technical competence, availability, identity, or fit for a project. Prices and plan limits can change. Define the test or edit scope, sizes, yarn, deadlines, compensation, confidentiality, intellectual property, file handling, expected feedback, and dispute process in writing before work starts. ### Account, payment, and exit - Access scope: Knit or crochet tester, designer, sample maker, or tech editor using one role-specific workflow. - Before an account: Browse public open testing calls and the provider's feature and pricing pages without signing in. - Free-account boundary: A free signup lets people look around, and testers participate without a platform charge. Designers and tech editors face different role boundaries. - Payment boundary: Designers can pay per call or job, buy non-expiring credits, or subscribe monthly. Tech editors need a separate monthly subscription to apply for jobs. - Cancellation or exit: The pricing page says monthly subscriptions can be canceled at any time, but it does not state when paid access ends or what happens to active tests or applications. - Saved work and data: Designers can download pattern-test feedback as CSV or XLSX. The checked pages do not establish a full account export or deletion route. ## 3. Garment POM Definition & Verification Record 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 Turning an ambiguous POM name, code, or diagram into a reproducible method before setting targets, tolerances, or inspection decisions ### What the source establishes The guide cites current ISO garment-measurement, body-measurement, and textile-conditioning standards plus NIST measurement-process guidance for repeatability and reproducibility; it requires organization-specific codes, added points, targets, and tolerances to remain explicitly controlled. ### Know before using The record does not reproduce licensed ISO measurement drawings, supply universal POM codes or targets, approve an internal method, prove measurement capability or product fit, or replace qualified technical-design, pattern, fit, quality, metrology, safety, and regulatory review. ## 4. Threadloop Sewing Pattern Database Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Makers - Location or jurisdiction: Global - Access: Free + paid - Format: Community - Source type: Community database - Linked page reviewed: 2026-07-28 - Next review due: 2027-01-24 ### 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. Current terms state that the free plan requires no card, paid upgrades start billing immediately, cancellation retains paid features through the current cycle, and the account then returns to free features. ### 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. ### Account, payment, and exit - Access scope: Sewer searching pattern records or organizing patterns, projects, fabric, notions, and private files. - Before an account: Browse the pattern database, guide, designers, publications, and public community areas without creating an account. - Free-account boundary: A free account needs no card and supports a stash, wishlist, projects, reviews, and personal organization. - Payment boundary: Plus adds PDF pattern storage, collections, saved searches, bulk editing, and other workflow features on monthly or annual billing. - Cancellation or exit: Cancel through an in-account link. Paid features remain through the current billing cycle, then the account returns to free features. - Saved work and data: The terms say submitted materials remain yours, but the checked public pages do not explain a full export or how stored PDFs behave after downgrade. Keep originals outside the platform. ## 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.
