| 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 | Individual and team 3D garment prototyping | Finding sustainability-focused suppliers and guidance |
| 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. | A virtual sample or coloured fit map is not proof of physical fit, comfort, construction quality, manufacturability, or graded-size approval. Results depend on pattern geometry, sewing, avatar measurements and pose, fabric physical-property data, trims, mesh, and simulation settings. Current releases have substantial hardware and learning requirements; validate representative fabrics, bodies, movements, and sewn samples physically. | A profile, match, uploaded credential, training credit, award, or platform ranking is not independent certification of a supplier or proof of current capability, performance, impact, capacity, or project fit. The platform's own ranking inputs and paid visibility affect discovery. Verify credentials with the issuer and check the legal entity, production site, claims, samples, references, terms, and compliance directly. |

| 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. | CLO's current product and support documentation covers linked 2D pattern work and 3D garment simulation on avatars, grading review by size, fabric and garment visualization, fit maps for stress, strain, pressure, and tightness, and rendering and presentation output. Current system requirements publish separate Windows and Apple Silicon baselines and higher recommendations for complex simulation and rendering. | Common Objective currently offers free individual and business profiles, personalised matches, supplier and content search, and limited monthly connection requests. Paid tiers unlock unlimited connections, additional content, training credits, and the CO Create sourcing workflow. Businesses enter their own profile information and upload certification or membership evidence; profile completeness, sustainability material, training credits, awards, and paid capabilities can influence visibility or ranking. |
