| Best for | Checking an EU supplier's stated VAT number and saving the dated validation response as one identity and invoicing control | Searching current and out-of-print sewing patterns | Understanding what a tech pack must control before using a template or releasing work | Replacing a discontinued or unavailable yarn |
| Know before using | A valid VAT number is not proof of manufacturing capability, facility ownership, authorized bank instructions, product origin, tax advice, quality, capacity, certification, labor conditions, or delivery; names and addresses may not be returned for every country, and temporary database outages occur. | 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. | An orientation rather than a completed product record; it does not supply a universal format, licensed standard content, measurements, tolerances, construction settings, labels, approvals, compliance conclusion, or product-release authority. | 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. |

| What the source establishes | VIES is the European Commission's online VAT Information Exchange System interface for querying national VAT databases to determine whether a submitted number is valid for intra-EU cross-border trade at the time of the request. | 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. | The guide cites current ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it explicitly separates those authorities from product-specific technical and market decisions. | 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. |
