| Know before using | 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. | 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. | A profile, match, uploaded credential, training credit, award, or platform ranking is not independent certification of a supplier or proof of current capability, performance, impact, capacity, or project fit. The platform's own ranking inputs and paid visibility affect discovery. Verify credentials with the issuer and check the legal entity, production site, claims, samples, references, terms, and compliance directly. |

| 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. | Fashion professional or supplier using content, profiles, connections, or a sourcing workflow. |
| 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. | Public content and explanation pages are visible while signed out; profiles, personalized matches, saved items, and connections require signup. |
| 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. | A free account provides a personal or business profile, limited monthly connections, free content, and up to three portfolio items. |
| 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. | PRO adds unlimited connections, paid content and training, more profile capacity, and business sourcing workflows. Monthly and annual routes use provider-set terms. |
| 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. | Cancel in the account by selecting downgrade. A business profile returns to the free version and only its first three portfolio items remain visible. |
| 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. | Profiles can contain files, work history, product galleries, and sustainability evidence. The current access and pricing pages do not establish full export or deletion; retain originals. |
| Source and review | ||||
| What the source establishes | 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. | 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. | Common Objective currently offers free individual and business profiles, personalised matches, supplier and content search, and limited monthly connection requests. Paid tiers unlock unlimited connections, additional content, training credits, and the CO Create sourcing workflow. Businesses enter their own profile information and upload certification or membership evidence; profile completeness, sustainability material, training credits, awards, and paid capabilities can influence visibility or ranking. |
