| Know before using | The platform combines stakeholder-contributed, public-list, facility-claimed, and partner data with different origins and update paths. A facility record, contributor connection, claim, certification field, or shared OS ID is not a quality endorsement, ownership finding, complete supplier relationship, current capacity statement, or due-diligence result. Inspect the source badges, contributors, dates, duplicates, claimed fields, and linked evidence, then verify the facility and intended business relationship directly. | 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. | A foundational library, not yet an exhaustive stitch encyclopedia. | 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. |

| What the source establishes | Open Supply Hub's current guide supports facility-name or OS ID, contributor, location, sector, parent-company, facility-type, processing-type, product-type, and worker-count searches, with contributor information visible on facility data. Manual search is open, a free account supports bounded data downloads, and paid services cover larger or programmatic access. | 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 linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. | 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. |
