| 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. | 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 visible drawdown is not automatically a complete, corrected, rights-cleared, or loom-compatible project plan. Full draft data and advanced tools require a renewing subscription, and historical sources can contain errors or unclear provenance. Check shafts, treadles, tie-up, sett, yarn, floats, repeats, copyright status, and WIF compatibility before committing a warp. | Free access does not grant commercial reproduction or sale rights; uses beyond one personal copy must be resolved with the designer or author. Knitty says it tries to avoid errors but disclaims responsibility for pattern and technique inaccuracies. Check the live page for corrections, verify gauge and measurements, and confirm permission before any commercial use. |

| Source and review | ||||
| 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. | 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. | Handweaving.net currently exposes the Ralph Griswold digital archive, document downloads, draft drawdown views, basic-account clipboards, and video tutorials without a paid subscription. Its subscription page reserves full drafts, WIF downloads, draft creation and editing, color tools, profile and block substitution, arrangement, repeats, and related browser tools for subscribers. The current page states that plans renew until canceled, cancellation takes effect at the next renewal, access remains until then, and refunds are not offered. | Knitty currently publishes web-only editorial issues containing original knitting and crochet patterns and articles. Its legal page states that patterns are free for one person's personal use, identifies each designer or author as the copyright holder, and explains that verified pattern corrections are posted in bright pink on the pattern page. |
