| Best for | Searching current and out-of-print sewing patterns | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge | Investigating an unknown textile without using flame, smoke, odor, or residue as composition, flammability, care, safety, or compliance proof |
| 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. | A shared nominal diameter does not make a knitting needle and crochet hook interchangeable or predict equal gauge or fabric. The reference is not a physical measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, or project approval. | The record does not identify a submitted textile, provide a home burn procedure, turn an observation into a fibre or blend result, choose a laboratory method, establish flammability or market compliance, validate a care instruction, or replace qualified laboratory, textile, conservation, safety, compliance, and legal review. |

| 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. | Rechecked July 28, 2026. The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows, aligns hooks and needles only when their nominal millimetre value matches, and leaves missing rows or aliases unfilled. | The guide cites current AATCC qualitative and quantitative fibre-analysis methods, the published ISO 1833-1 quantitative-analysis principles, ASTM's withdrawn D276 status and reinstatement work item, current FTC U.S. textile-label guidance, and current CPSC clothing-textile flammability guidance. |
