| 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. | This is a unit-translation reference. It does not select, approve, or change a seam allowance; establish a universal fraction; interpret an unstated cutting or stitching line; or replace the exact pattern version, controlled specification, material and seam evidence, sample, production method, equipment, tolerance, or release authority. | 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. |

| Before an account | Browse the pattern database, guide, designers, publications, and public community areas without creating an account. | Not yet reviewed at this level. | Search and explore facility records without payment. The provider states that the platform is free to search, contribute to, and explore. |
| Free-account boundary | A free account needs no card and supports a stash, wishlist, projects, reviews, and personal organization. | Not yet reviewed at this level. | A free account supports search, contribution, profile viewing, and download of up to 5,000 production locations. |
| Payment boundary | Plus adds PDF pattern storage, collections, saved searches, bulk editing, and other workflow features on monthly or annual billing. | Not yet reviewed at this level. | Paid products support continuous API access, custom or bulk data work, and embedded maps. Cost and commitment vary by product and scale. |
| Cancellation or exit | Cancel through an in-account link.

Resolve those terms in the order or contract before integration. |
| 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. | Not yet reviewed at this level. | The free account includes a bounded download; paid products add custom exports and API access. Contributor, claimed, and partner fields have different provenance and update paths. |
| Source and review | |||
| 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. | NIST states that one inch is exactly 25.4 millimetres, and the SI decimal relationship makes one centimetre equal to 10 millimetres. The tool uses those factors, displays rounded equivalents, exposes the size difference to the nearest 1/16 inch when converting to inches, and preserves valid value, source-unit, and target-unit state in the URL. | 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. |
