| 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. | Coverage is quilting-specific and uneven by country; businesses can pay for enhanced features, and community or owner updates do not verify inventory, service quality, hours, or availability. | A measurement-generated draft is a starting block, not independent evidence of body capture, comfort, mobility, balance, garment ease, or production fit. The result depends on measurement accuracy, supported ranges, formula assumptions, selected options, and output handling. Review the service's privacy terms before storing body data and sew a representative toile before design, grading, or production use. | 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. |

| 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. | QuiltMap describes free public search and free basic listings, community submissions and claims, and country routes covering North America, Europe, Japan, South Korea, and Australia. | PatternLab London's current drafting page says a user creates a measurement profile, selects a basic block or sloper, adjusts fit, dart placement, length, seam allowance, and sleeve options, then downloads the generated result as tiled PDF, AI, or SVG. The live catalogue names bodice, dress, trouser, and stretch blocks and displays a price before purchase. | 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. |
