# Stitch Authority resource comparison Generated: 2026-07-28T10:15:06.801Z 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. Handweaving.net Draft Archive Permanent record: Source page: - Primary job: Learn techniques - Area: Techniques & repair - For: Makers - Location or jurisdiction: Global - Access: Free + paid - Format: Reference - Source type: First-party platform - Linked page reviewed: 2026-07-28 - Next review due: 2027-01-24 ### Best for Researching loom-ready weaving structures and drafts ### What the source establishes Handweaving.net currently exposes the Ralph Griswold digital archive, document downloads, draft drawdown views, basic-account clipboards, and video tutorials without a paid subscription. Its subscription page reserves full drafts, WIF downloads, draft creation and editing, color tools, profile and block substitution, arrangement, repeats, and related browser tools for subscribers. The current page states that plans renew until canceled, cancellation takes effect at the next renewal, access remains until then, and refunds are not offered. ### Know before using A visible drawdown is not automatically a complete, corrected, rights-cleared, or loom-compatible project plan. Full draft data and advanced tools require a renewing subscription, and historical sources can contain errors or unclear provenance. Check shafts, treadles, tie-up, sett, yarn, floats, repeats, copyright status, and WIF compatibility before committing a warp. ### Account, payment, and exit - Access scope: Weaver deciding whether viewing a draft is enough or a working WIF file and editing tools are required. - Before an account: Browse the Ralph Griswold archive, download archive documents, and view draft drawdowns without a paid subscription. - Free-account boundary: A free basic account adds clipboards. Full drafts, working files, and browser drafting tools remain outside the free account. - Payment boundary: A monthly or annual recurring subscription unlocks full drafts, WIF downloads, and browser drafting and editing tools. - Cancellation or exit: Cancel from the account page. Renewal stops at the next renewal date, paid access remains until then, and the provider states that refunds are not given. - Saved work and data: The checked page does not explain bulk export or deletion for clipboards or contributed drafts. Retain local copies of WIF files and source material before exit. ## 2. 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. ## 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: 2026-07-28 - Next review due: 2027-01-24 ### Best for Building a substitution shortlist for a discontinued or unavailable yarn before checking quantity, availability, and a representative swatch ### 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 suggestions. Result filters can exclude animal, animal-derived, synthetic, or plant fibre groups and use a subjective $ to $$$$$ price indicator. The site does not accept user-entered yarn details, individual shade cards, or expose an API. Each yarn page provides a data-issue route. ### Know before using A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Records can be incomplete or wrong, price bands are approximate, availability varies by country and seller, and shade-level matching is unavailable. YarnSub says affiliate status does not change suggestions, but equally rated matches are ordered by brand popularity. Confirm required gauge, total length, fibre behavior, construction, care, colour, dye lot, accessibility, price, availability, and seller terms, then make and assess a representative swatch before committing. ### Account, payment, and exit - Access scope: Maker comparing a replacement for a named yarn before buying. - Before an account: Search a named yarn, inspect suggested substitutes, and filter by fibre and approximate price band without creating an account. - Free-account boundary: The checked core substitution route does not require an account, and the FAQ does not offer user-entered yarn records. - Payment boundary: No subscription is presented for the core route. Affiliate retailer links and optional donations help fund the site; equal-rated matches are ordered by brand popularity. - Cancellation or exit: There is no account or recurring plan to cancel for the core route. The newsletter has a separate unsubscribe link. - Saved work and data: YarnSub does not expose an API and does not accept user-entered yarn details. Use the data-issue link on a yarn page for corrections. ## 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.
