| Know before using | The result is a numerical unit conversion, not a new measurement or conformance decision; it does not establish sample or lot representativeness, significant digits, drape, warmth, opacity, thickness, stretch, strength, shrinkage, durability, sewability, end use, target, or tolerance. | Repair Cafés are volunteer events rather than guaranteed commercial services, and each location sets its schedule, item scope, expertise, accessibility, parts policy, and capacity; confirm that clothing or textile help is available before traveling and expect to participate in the repair. | 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 | The calculator uses the NIST SP 811 Appendix B.8 conversion from avoirdupois ounces per square yard to kilograms per square metre and links to a source-reviewed fabric mass record for method, sampling, conditioning, and product controls. | The foundation's current public search reports thousands of registered Repair Cafés across dozens of countries, and its organizer manual includes clothing stations with sewing machines, hand tools, zips, buttons, patches, elastic, darning supplies, and wool-repair equipment. | 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. |
