| Best for | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge | Planning a sewing, knitting, or crochet pattern test | Searching current and out-of-print sewing patterns | Requesting apparel-production proposals |
| Know before using | A shared nominal diameter does not make a knitting needle and crochet hook interchangeable or predict equal gauge or fabric. The reference is not a physical measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, or project approval. | The workflow is not a contract or quality certification; local legal duties and technical review may still apply. | 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 profile, proposal, match, or escrow status does not establish factory ownership, identity, capacity, workmanship, quality systems, labour or chemical compliance, delivery performance, contract enforceability, or project fit. Verify the legal and production entities, references, site and subcontracting, samples, compliance evidence, specifications, terms, and remedies directly. |

| Free-account boundary | Not yet reviewed at this level. | Not yet reviewed at this level. | A free account needs no card and supports a stash, wishlist, projects, reviews, and personal organization. | The current first-party FAQ gives brands a seven-day trial and says service providers can join free. Access differs by role: brands create and publish enquiries; completed service-provider profiles can appear in search and browse enquiries. |
| Payment boundary | Not yet reviewed at this level. | Not yet reviewed at this level. | Plus adds PDF pattern storage, collections, saved searches, bulk editing, and other workflow features on monthly or annual billing. | After the brand trial, the FAQ routes brands to monthly or annual subscription access. A supplier proposal, brand-paid platform commission, production payment, and optional escrow are separate transaction costs rather than the subscription itself. |
| Cancellation or exit | Not yet reviewed at this level. | Not yet reviewed at this level. | Cancel through an in-account link. Paid features remain through the current billing cycle, then the account returns to free features. | The FAQ routes account cancellation through Account settings and says the trial can be canceled. The checked public pages do not establish when subscription access ends, refund terms, or what happens to active enquiries, messages, proposals, or escrow after cancellation. |
| Saved work and data | Not yet reviewed at this level. | Not yet reviewed at this level. | The terms say submitted materials remain yours, but the checked public pages do not explain a full export or how stored PDFs behave after downgrade. Keep originals outside the platform. | Accounts can hold project details, uploads, messages, proposals, agreements, and invoices. Invoices and individual attachments have download routes, but the checked public pages do not establish a complete account export or post-cancellation retention and deletion path. Keep original files and decision records outside the platform. |
| Source and review | ||||
| What the source establishes | Rechecked July 28, 2026. The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows, aligns hooks and needles only when their nominal millimetre value matches, and leaves missing rows or aliases unfilled. | The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. | 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. | Sewport's current brand workflow starts with an account and guided project enquiry, then exposes proposals from garment factories and production specialists. The platform tells brands to compare profiles, portfolios, location, price, and communication, then record service, delivery, payment, and contract terms in a formal proposal. Its service-provider workflow includes factories, sample studios, pattern cutters, tech-pack makers, sourcing specialists, and material suppliers, with optional split-payment escrow. |
