| 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. | 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. | This is a mixed, paid-listing association directory, not a complete map of Canadian apparel production. A listing, membership, category, or company description does not establish Canadian manufacturing, current identity, factory ownership, capability, capacity, minimums, availability, compliance, or project fit. Confirm the actual production site, subcontracting, references, samples, terms, and credentials directly. |

| 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. | 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. | The Canadian Apparel Federation's public directory currently includes apparel manufacturers, distributors, material and trim suppliers, logistics businesses, technology services, and other industry companies. Its listing page states that members may list free after membership approval, while non-members can register and pay for a one- or five-year listing. |
