# Stitch Authority resource comparison Generated: 2026-08-05T08:04:24.217Z 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. Apparel Grade-Rule & Size-Run Validation Record Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - 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 Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence ### What the source establishes The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments. ### Know before using The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review. ## 3. Singapore NLB MakeIT Sewing Access Permanent record: Source page: - Primary job: Learn techniques - Area: Techniques & repair - For: Makers - Location or jurisdiction: Singapore ยท Southeast Asia - Access: Free account - Format: Reference - Source type: Government guidance - Linked page reviewed: 2026-07-16 - Next review due: 2026-10-14 ### Best for Finding beginner-supported sewing and upcycling sessions or booking guided self-service sewing-machine access through Singapore public libraries ### What the source establishes Singapore's National Library Board describes MakeIT at Libraries as a beginner-friendly programme with sewing and upcycling areas, guided facilities, free workshops and materials for NLB members, an age recommendation of 15 and above, and locations at Jurong, Tampines, Woodlands, and Punggol. The MakeIT Yourself page, last updated December 30, 2025, says users of any experience can book sewing machines and use written guides, pre-use checks, safety and help instructions, cleanup, and fault reporting. ### Know before using This is an in-person Singapore route that requires current NLB membership and booking conditions. It does not promise that every location, machine, time slot, workshop, material, staff member, or access accommodation is always available. Some equipment requires certification. Booking or workshop participation is not a professional qualification, repair-service engagement, or proof of independent machine competence. Confirm eligibility, opening hours, dates, availability, age guidance, accessibility, machine rules, permitted projects, materials, and safety directly with NLB. ## 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.
