It is not a recommendation, provider approval, compliance decision, or record of project-specific due diligence. ## 1. Tech Pack Definition, Contents & Limits 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: 2026-07-27 - Next review due: 2027-07-27 ### Best for Understanding what a tech pack must control before using a template or releasing work ### What the source establishes The guide cites published ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it discloses that ISO 10013:2021's 2026 systematic review is at close-of-review stage and separates every cited authority from product-specific technical and market decisions. ### Know before using An orientation rather than a completed product record; it does not supply a universal format, licensed standard content, measurements, tolerances, construction settings, labels, approvals, compliance conclusion, or product-release authority. ## 2. 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. ## 3. QUT TextileR Knowledge Base Permanent record: Source page: - Primary job: Choose materials - Area: Materials - For: Both - Location or jurisdiction: Australia ยท Oceania - Access: Open access - Format: Reference - Source type: First-party platform - Linked page reviewed: 2026-07-26 - Next review due: 2027-01-22 ### Best for Comparing common fibre types and blends by typical use and care before choosing a project material, then following the cited source when the decision needs testing or current claim evidence ### What the source establishes The live QUT index says the knowledge base is designed to help users choose an appropriate textile and extend garment use. It links 14 topics: nine named fibre pages, textile blends, re-making, reuse, recycling, and repair. Checked silk, polyester, wool, and blend pages organize information under overview, common fabrics, context of use, care, recycling, and further reading where applicable. QUT identifies TextileR as a research group and publishes named researchers, publications, objectives, and a direct contact. ### Know before using This is a general educational reference, not a neutral material ranking, complete fibre encyclopedia, specification, test report, sourcing database, lifecycle assessment, certification, safety procedure, or proof of a product claim. Coverage and citation depth vary by page, and some environmental, care, performance, or end-of-life statements are broad. Fibre name alone does not establish a fabric's construction, blend percentage, finish, quality, behavior, or suitability. Confirm the exact composition, construction, finish, care label, sample behavior, test evidence, certification scope, and project requirements with the responsible supplier, scheme, laboratory, or specialist. ## 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.
