| Know before using | This is a unit-translation reference. It does not select, approve, or change a seam allowance; establish a universal fraction; interpret an unstated cutting or stitching line; or replace the exact pattern version, controlled specification, material and seam evidence, sample, production method, equipment, tolerance, or release authority. | SwatchOn's supplier status, counts, trust language, specifications, prices, availability, and account benefits are provider or supplier statements that can change. They do not independently establish fibre identity, performance, certification validity, mill ownership, production capacity, colour continuity, delivery, duty, or commercial fit. Review representative samples, test data, current certificates, the contracting entity, order terms, return limits, and landed logistics before purchase. | 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. | The company count is a changing platform claim. Search fields, profiles, certificates, locations, and account access do not independently verify the legal entity, factory ownership, capability, capacity, certificate validity or scope, compliance performance, delivery, or project fit. Confirm the site and subcontracting, credentials with issuers, samples, audits when appropriate, specifications, contracts, and commercial terms. |

| Access scope | Not yet reviewed at this level. | Business or individual buyer sourcing fabric, trims, swatches, or custom printing through SwatchOn's marketplace and order workflow. | Sewer searching pattern records or organizing patterns, projects, fabric, notions, and private files. | Not yet reviewed at this level. |
| Before an account | Not yet reviewed at this level. | Read the marketplace scope, material-category pages, service explanations, help articles, calculators, and legal policies. The checked signed-out pages do not expose the full product library, wholesale ordering, or sample-purchase workflow. | Browse the pattern database, guide, designers, publications, and public community areas without creating an account. | Not yet reviewed at this level. |
| Free-account boundary | Not yet reviewed at this level. | After email verification, business and individual accounts receive product-library, wholesale-order, and sample-purchase access. A completed business profile and business proof add a sourcing manager and conditional swatch credits; the terms allow identity, business, or payment verification and account rejection. | A free account needs no card and supports a stash, wishlist, projects, reviews, and personal organization. | Not yet reviewed at this level. |
| Payment boundary | Not yet reviewed at this level. | The checked first-party pages disclose no recurring platform subscription. Buyers pay per sample or product order plus the checkout currency, shipping, duties, taxes, adjustments, and any agreed service fees; complimentary swatches or credits are conditional rather than universal free access. | 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. |
| Cancellation or exit | Not yet reviewed at this level. | There is no subscription plan to cancel on the checked pages. The terms say a user may stop using the platform, while the privacy policy routes access, correction, portability, and deletion requests through support and permits retention for legal, accounting, dispute, and agreement-enforcement needs. | 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. |
| Saved work and data | Not yet reviewed at this level. | The platform can hold account and verification data, carts and orders, payment and shipping records, customs documents, artwork, supplier messages, reviews, and support tickets. The privacy policy offers copy, portability, correction, and deletion requests, but does not state a self-service full export, exact format, completion time, or complete deletion of retained transaction records. | 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. |

| What the source establishes | NIST states that one inch is exactly 25.4 millimetres, and the SI decimal relationship makes one centimetre equal to 10 millimetres. The tool uses those factors, displays rounded equivalents, exposes the size difference to the nearest 1/16 inch when converting to inches, and preserves valid value, source-unit, and target-unit state in the URL. | SwatchOn's current marketplace page exposes fabrics, trims, and prints, with swatch samples, in-stock catalogue colours, low-order-quantity options, and global logistics support. Current account guidance places the full product library, wholesale ordering, and sample purchasing behind email verification, while the terms describe supplier-provided listings, per-order payment, cross-border charges, sample limits, and marketplace responsibility. | 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. | FOURSOURCE's current public network page presents an operator-reported global company count and country or territory search. It says logged-in users can narrow results by compliance certificates, product groups, fabric types, target groups, minimum order quantities, and other fields, with a free-trial and supplier sign-up route. |
