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.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.

Source and review
What the source establishesThe public directory exposes location and shop-type discovery, while the platform states that business listings have no monthly fee and revenue comes from affiliate partnerships and marketplace commissions.The guide cites current ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it explicitly separates those authorities from product-specific technical and market decisions.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.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.
