| Best for | Comparing an original and candidate yarn without treating the 0-7 category system, a familiar retail name, ply count, or WPI result as proof of interchangeability | Searching current and out-of-print sewing patterns |
| Know before using | The record does not verify a yarn label, certify fibre or origin, provide a regional ply crosswalk, predict exact quantity or cost, approve care, establish allergy safety, or prove finished fit, wear, durability, availability, or project success. | 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 guide cites current Craft Yarn Council weight-system, FAQ, WPI, and hook-and-needle guidance plus current ASTM tex-designation and ISO yarn-linear-density sources; it distinguishes voluntary craft category, subjective screen, package quantity, measured property, finished gauge, and project decision. | 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. |
