# Stitch Authority resource comparison Generated: 2026-07-28T17:08:12.590Z 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. CPSC Certificate eFiling Permanent record: Source page: - Primary job: Check standards - Area: Standards - For: Apparel brands - Location or jurisdiction: United States · North America - Access: Open access - Format: Reference - Source type: Government guidance - Linked page reviewed: 2026-07-16 - Next review due: 2026-10-14 ### Best for Planning the current CPSC certificate-data handoff for regulated imports with the importer, finished-product certifier, customs broker, and entry records ### What the source establishes CPSC operates the eFiling portal with role-specific importer, broker, applicability, Product Registry, regulated-product, laboratory, ACE, FAQ, video, and document-library routes. The certificate final rule took effect July 8, 2026 for covered non-FTZ products, with separate timing for covered FTZ entries. ### Know before using The portal does not decide whether a product requires certification, identify the correct rules or certificate data, classify an entry, replace the current 16 CFR part 1110 text, or reconcile a filing to an actual shipment. Effective dates and workflows differ by entry route; use current CPSC, CBP, customs, product-safety, and legal review. ## 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. Peru Minedu Patronaje Program Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Both - Location or jurisdiction: Peru · Latin America & Caribbean - Access: Free download - Format: Reference - Source type: Official registry - Linked page reviewed: 2026-07-16 - Next review due: 2026-10-14 ### Best for Comparing a patternmaking curriculum, qualification claim, learning plan, or portfolio brief with Peru's published national program competencies and achievement indicators ### What the source establishes Peru's Ministry of Education currently lists Patronaje under garment manufacturing in the National Catalogue of Training Offerings, whose industry-manufacturing orientation page records a last change on June 4, 2026. The official program is code C0714-2-002 at technical level, with 80 credits and 1,760 hours. Its seven competency units cover obtaining base and graded garment patterns from a technical specification; preparing, sewing, and validating a prototype; manually or digitally laying out pattern pieces; spreading material; cutting; preparing cut pieces for production; and joining garment pieces. The connected achievement indicators name specifications, measurements, seam information, trims, finishes, base size and scale, client requirements, material optimization, cutting orders, occupational safety, and production handoff. ### Know before using This is a national program reference whose published program version is marked updated November 6, 2018, although Minedu still lists Patronaje in the current CNOF. It is not a current course-opening directory, enrollment offer, school recommendation, complete syllabus, teaching-quality assessment, professional license, practitioner certification, ready pattern, universal size or grading system, product-fit proof, or evidence that an individual completed the competencies. Confirm the current catalogue status, authorized institution, offered plan, admission, delivery, assessment, title, local recognition, equipment, software, safety, cost, accessibility, and product-specific pattern and fit evidence directly. ## 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.
