It is not a recommendation, provider approval, compliance decision, or record of project-specific due diligence. ## 1. Pattern Grading & 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: 2026-07-27 - Next review due: 2027-07-27 ### 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. ## 2. Yarn Database EU Dyers and Makers Permanent record: Source page: - Primary job: Choose materials - Area: Yarn - For: Makers - Location or jurisdiction: European Union - Access: Open access - Format: Directory - Source type: Community database - Linked page reviewed: 2026-07-15 - Next review due: 2027-01-11 ### Best for Finding independent EU yarn or fibre dyers with off-Ravelry purchase routes ### What the source establishes The individually researched database offers free listings and sortable yarn, fibre, designer, editor, accessory, and location views; the EU page spans multiple countries and direct seller profiles. ### Know before using It is one curator's intentionally selective, off-Ravelry-oriented database, inventories change, and paid supporters can receive rotating priority placement; verify availability, fibre claims, shipping, and terms directly. ## 3. 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. ## 4. MarediModa Virtual Showroom Permanent record: Source page: - Primary job: Choose materials - Area: Materials - For: Apparel brands - Location or jurisdiction: Europe & Mediterranean - Access: Open access - Format: Directory - Source type: First-party platform - Linked page reviewed: 2026-07-15 - Next review due: 2027-01-11 ### Best for Finding specialist stretch fabrics, embroidery, lace, and components in the Euro-Mediterranean supply base ### What the source establishes The public showroom filters participating companies by plain, printed, and yarn-dyed fabrics, embroideries and laces, accessories, and design studios for specialist apparel markets. ### Know before using It is a curated specialty-show community rather than complete regional coverage; confirm current participation, production geography, technical fit, minimums, capacity, and terms directly. ## Next checks 1.
