| Best for | Searching current and out-of-print sewing patterns | Finding sustainability-focused suppliers and guidance | Checking which U.S. alias the current Craft Yarn Council table gives a known metric package size before confirming project gauge | Translating a seam allowance already stated by a pattern or controlled specification |
| 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. | 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. | The reference is not a dimensional measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, gauge result, or proof that a proposed tool will produce the required fabric. | 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. |

| 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. | 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. | Rechecked July 27, 2026. The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows and follows the Council's warning that company letter and number labels vary; blank aliases remain blank instead of being inferred. | 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. |
