| Best for | Planning the current CPSC certificate-data handoff for regulated imports with the importer, finished-product certifier, customs broker, and entry records | Translating the same fabric mass-per-area result between metric and U.S. customary listings | Finding independent EU yarn or fibre dyers with off-Ravelry purchase routes | Searching current and out-of-print sewing patterns |
| Know before using | The portal does not decide whether a product requires certification, identify the correct rules or certificate data, classify an entry, replace the current 16 CFR part 1110 text, or reconcile a filing to an actual shipment. Effective dates and workflows differ by entry route; use current CPSC, CBP, customs, product-safety, and legal review. | The result is a numerical unit conversion, not a new measurement or conformance decision; it does not establish sample or lot representativeness, significant digits, drape, warmth, opacity, thickness, stretch, strength, shrinkage, durability, sewability, end use, target, or tolerance. | 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. |

| What the source establishes | CPSC operates the eFiling portal with role-specific importer, broker, applicability, Product Registry, regulated-product, laboratory, ACE, FAQ, video, and document-library routes. The certificate final rule took effect July 8, 2026 for covered non-FTZ products, with separate timing for covered FTZ entries. | The calculator uses the NIST SP 811 Appendix B.8 conversion from avoirdupois ounces per square yard to kilograms per square metre and links to a source-reviewed fabric mass record for method, sampling, conditioning, and product controls. | 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. |
