| Best for | Translating the same fabric mass-per-area result between metric and U.S. customary listings | Searching current and out-of-print sewing patterns | Finding independent EU yarn or fibre dyers with off-Ravelry purchase routes | Building a substitution shortlist for a discontinued or unavailable yarn before checking quantity, availability, and a representative swatch |
| 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. | 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. | It is one curator's intentionally selective, off-Ravelry-oriented database, inventories change, and paid supporters can receive rotating priority placement; verify availability, fibre claims, shipping, and terms directly. | A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Records can be incomplete or wrong, price bands are approximate, availability varies by country and seller, and shade-level matching is unavailable. YarnSub says affiliate status does not change suggestions, but equally rated matches are ordered by brand popularity. Confirm required gauge, total length, fibre behavior, construction, care, colour, dye lot, accessibility, price, availability, and seller terms, then make and assess a representative swatch before committing. |

| Source and review | ||||
| 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. | 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. | The individually researched database offers free listings and sortable yarn, fibre, designer, editor, accessory, and location views; the EU page spans multiple countries and direct seller profiles. | YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggestions. Result filters can exclude animal, animal-derived, synthetic, or plant fibre groups and use a subjective $ to $$$$$ price indicator. The site does not accept user-entered yarn details, individual shade cards, or expose an API. Each yarn page provides a data-issue route. |
