# Stitch Authority resource comparison Generated: 2026-08-02T08:15:41.945Z 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. Pattern Testers Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Apparel brands - Location or jurisdiction: Global - Access: Free + paid - Format: Software - Source type: First-party platform - Linked page reviewed: 2026-07-21 - Next review due: 2027-01-17 ### Best for Coordinating an independent sewing-pattern test ### What the source establishes Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed. ### Know before using The interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer. ## 3. TUKAcad Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Both - Location or jurisdiction: Global - Access: Paid - Format: Software - Source type: First-party platform - Linked page reviewed: 2026-07-21 - Next review due: 2027-01-17 ### Best for 2D patternmaking and grading with public plan tiers ### What the source establishes Tukatech's current TUKAcad page publishes monthly Learning and Professional editions for digital patternmaking and grading, with a higher tier adding marker making, data import and export, digitizing, cut-data optimization, and yield reports. It discloses plan limits on pattern pieces, graded sizes, and marker dimensions, plus built-in help, block templates, a trial, Windows requirements, and the Windows-on-Mac route. ### Know before using TUKAcad is Windows software; the official Mac route requires a separate virtual Windows environment. Pattern-piece, graded-size, marker, import and export, digitizing, and production-output capabilities vary materially by paid tier. A CAD file or marker report does not prove fit or factory readiness, so verify formats, grade rules, seam and production data, hardware, training, and downstream compatibility before subscribing. ## 4. Textile Museum of Canada Learning Hub Permanent record: Source page: - Primary job: Learn techniques - Area: Techniques & repair - For: Makers - Location or jurisdiction: Canada ยท North America - Access: Free + paid - Format: Reference - Source type: First-party platform - Linked page reviewed: 2026-07-17 - Next review due: 2027-01-13 ### Best for Exploring textile techniques and textile care through a national museum public programs, recorded workshops, and self-directed online resources ### What the source establishes The Textile Museum of Canada, a national institution in Toronto supported by public arts funders including the Canada Council for the Arts and the Government of Canada, states on its learning page that it supports lifelong learning through public programs, including hybrid online and in-person workshops, artist talks, and tours, an archive of recorded programs and workshops, education guides tied to exhibitions, and a caring-for-your-textiles conservation section with curated resources. The museum also facilitates workshops at Toronto Public Library branches and through a Community Makers program. ### Know before using This is a museum learning hub, not a structured technique curriculum, a qualification, a certification, a practitioner directory, or proof of skill. In-person and scheduled programs may be ticketed, time-limited, or Toronto-based, and recorded content and online resources vary in depth and topic. Confirm the current program schedule, access, cost, format, and topic coverage before relying on it for a specific technique. ## 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.
