| 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. | The 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. | This is a unit-translation reference. It does not select, approve, or change a seam allowance; establish a universal fraction; interpret an unstated cutting or stitching line; or replace the exact pattern version, controlled specification, material and seam evidence, sample, production method, equipment, tolerance, or release authority. |

| 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. | Lectra'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. | NIST states that one inch is exactly 25.4 millimetres, and the SI decimal relationship makes one centimetre equal to 10 millimetres. The tool uses those factors, displays rounded equivalents, exposes the size difference to the nearest 1/16 inch when converting to inches, and preserves valid value, source-unit, and target-unit state in the URL. |
