| Know before using | 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. | A profile, match, uploaded credential, training credit, award, or platform ranking is not independent certification of a supplier or proof of current capability, performance, impact, capacity, or project fit. The platform's own ranking inputs and paid visibility affect discovery. Verify credentials with the issuer and check the legal entity, production site, claims, samples, references, terms, and compliance directly. | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. | 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 | 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. | Common Objective currently offers free individual and business profiles, personalised matches, supplier and content search, and limited monthly connection requests. Paid tiers unlock unlimited connections, additional content, training credits, and the CO Create sourcing workflow. Businesses enter their own profile information and upload certification or membership evidence; profile completeness, sustainability material, training credits, awards, and paid capabilities can influence visibility or ranking. | The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. | 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. |
