Know before usingThe page does not publish price and its product-quality, error-prevention, data-loss, and fit statements are vendor claims. Capabilities vary across Essential, Classic, Expert, 3D, and add-ons. Confirm licenses, modules, support, system and file requirements, then pilot approved blocks, grade rules, supplier reopen, material and mannequin data, plot or cut outputs, and risk-appropriate physical fit and production checks.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 suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Yarn records can be incomplete or wrong, prices and availability vary by market, and the site uses affiliate links. Confirm the required gauge, total length, fibre behavior, construction, care, color, dye lot, accessibility, and seller terms, then make and assess a representative swatch before committing.The reference is not a dimensional measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, gauge result, or proof that a proposed tool will produce the required fabric.

Source and review
What the source establishesLectra's current Modaris page identifies version 2025.2 as the latest listed release and describes a one- to three-year subscription with two releases per year. The modular range covers base-pattern creation and modification, grading and industrialization, native-file supplier work, pattern libraries, synchronized 2D and 3D prototypes, configurable or imported mannequins, and separate conversion and consumption-estimate add-ons.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.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 suggested replacements, and each yarn page provides a route to report source-data problems.The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows and follows the Council's warning that company letter and number labels vary; blank aliases remain blank instead of being inferred.
