| Best for | Finding independent EU yarn or fibre dyers with off-Ravelry purchase routes | Searching current and out-of-print sewing patterns | Understanding what a tech pack must control before using a template or releasing work | Turning a known project length and candidate package size into a transparent buying estimate while keeping specimen, finished-fabric, care, and supply decisions separate |
| Know before using | It is one curator's intentionally selective, off-Ravelry-oriented database, inventories change, and paid supporters can receive rotating priority placement; verify availability, fibre claims, shipping, and terms directly. | 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. | The tool does not verify label values, convert between metres and yards, identify fibre or yarn diameter, assign a yarn-weight category, predict gauge or fabric, prescribe reserve, guarantee required quantity, check dye-lot supply, score candidates, or approve a substitution. A representative treated specimen and project-specific fabric, care, wear, comfort, supply, and quantity review remain required. |

| Source and review | ||||
| What the source establishes | The individually researched database offers free listings and sortable yarn, fibre, designer, editor, accessory, and location views; the EU page spans multiple countries and direct seller profiles. | 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. | The guide cites published ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it discloses that ISO 10013:2021's 2026 systematic review is at close-of-review stage and separates every cited authority from product-specific technical and market decisions. | The planner performs visible arithmetic only on user-entered project length, reserve, package length, package mass, and price. Its connected source-reviewed guide cites the current Craft Yarn Council category, FAQ, WPI, and hook-and-needle guidance plus ASTM and ISO linear-density sources, and explicitly separates label comparison from substitution approval. |
