| Best for | Searching current and out-of-print sewing patterns | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge | Evaluating an enterprise material-sourcing workflow after requirements are defined | Running knit or crochet pattern tests |
| Know before using | 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 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 public site’s workflow, security, validation, and outcome statements are operator claims rather than independent performance evidence. The Sourcing Hub, Marketplace, and Digital Sourcing Platform have separate terms and must not be treated as one identical product. Supplier content, uploaded certificates, and AI suggestions are leads, not independent verification. Verify the exact product and Order, material identity and performance, certificate issuer and validity, supplier capability, samples, price, availability, commercial terms, data permissions, and any AI output before a sourcing decision. | The platform is for knit and crochet rather than sewing, and a profile, application, rating, or platform listing does not prove technical competence, availability, identity, or fit for a project. Prices and plan limits can change. Define the test or edit scope, sizes, yarn, deadlines, compensation, confidentiality, intellectual property, file handling, expected feedback, and dispute process in writing before work starts. |

| Access scope | Sewer searching pattern records or organizing patterns, projects, fabric, notions, and private files. | Not yet reviewed at this level. | Business brand, supplier, manufacturer, or sourcing team considering Material Exchange’s current invite-only Sourcing Hub powered by Frank for early-stage material and supplier work. | Knit or crochet tester, designer, sample maker, or tech editor using one role-specific workflow. |
| Before an account | Browse the pattern database, guide, designers, publications, and public community areas without creating an account. | Not yet reviewed at this level. | Read the public workflow, security, and legal explanations and request a demo. The checked signed-out pages do not expose the live Sourcing Hub, supplier or material catalogue, configured feature scope, trial entitlement, or price. | Browse public open testing calls and the provider's feature and pricing pages without signing in. |
| Free-account boundary | A free account needs no card and supports a stash, wishlist, projects, reviews, and personal organization. | Not yet reviewed at this level. | Sourcing Hub registration is invite only and managed by the Material Exchange team. An Order defines each organisation’s authorized service scope and term; the terms say some services may be free and trials may be offered, but the public pages do not promise either. Individualised logins may not be shared. | A free signup lets people look around, and testers participate without a platform charge. Designers and tech editors face different role boundaries. |
| Payment boundary | Plus adds PDF pattern storage, collections, saved searches, bulk editing, and other workflow features on monthly or annual billing. | Not yet reviewed at this level. | No public fee amount is disclosed. Orders or separate agreements define subscription and service charges; paid services may combine a one-time charge with automatically renewing monthly, quarterly, or annual charges. Orders are described as non-cancellable and non-refundable. Supplier transaction fees, sample shipping, scanning, customs, taxes, and separately negotiated services can be additional costs. | Designers can pay per call or job, buy non-expiring credits, or subscribe monthly. Tech editors need a separate monthly subscription to apply for jobs. |
| Cancellation or exit | Cancel through an in-account link. Paid features remain through the current billing cycle, then the account returns to free features. | Not yet reviewed at this level. | Users terminate through support, while paid-service exit can also depend on a separate agreement. The public terms say access can continue through the current term, there is no prorated refund, and renewal stops after termination; they also warn that account termination may destroy associated content. Confirm the required notice, receipt, final access date, and content-return terms in the Order before paying. | The pricing page says monthly subscriptions can be canceled at any time, but it does not state when paid access ends or what happens to active tests or applications. |
| Saved work and data | 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. | Not yet reviewed at this level. | The Sourcing Hub can hold company and user details, sourcing briefs, supplier and material records, files, certificates, prices, compliance data, messages, samples, and detailed transaction records. Users retain ownership of submitted content, but termination may destroy it. The data notice covers personal-data access and portability and says residual copies may remain in active servers or backups; it does not document a self-service complete business-content export, format, or timing. Keep source files outside the platform and negotiate business-data return or export terms. | Designers can download pattern-test feedback as CSV or XLSX. The checked pages do not establish a full account export or deletion route. |
| Source and review | ||||
| What the source establishes | 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. | 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. | Material Exchange’s current site presents an enterprise early-stage sourcing workflow and routes prospective customers to a demo. Its Sourcing Hub terms, last modified October 24, 2025, define invite-only registration, AI-assisted material discovery, sample requests, bulk inquiries, negotiation, order-defined service access, subscriptions, and supplier transaction fees. The same terms say Material Exchange cannot verify uploaded certificate statements. | Yarnpond's current pages let knit and crochet designers publish public or private testing calls, select applicants, communicate with test teams, set milestones, collect feedback, post sample-making calls, and advertise tech-editing jobs. Testers can participate without charge, while designers pay per testing or job post, use credits that the pricing page says do not expire, or use a monthly subscription that the page says can be canceled. |
