| 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 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. | 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. |

| Access scope | Sewer searching pattern records or organizing patterns, projects, fabric, notions, and private files. | Apparel brand requesting production proposals or service provider responding to enquiries through Sewport's project workflow. | Not yet reviewed at this level. |
| Before an account | Browse the pattern database, guide, designers, publications, and public community areas without creating an account. | Read the brand and service-provider workflow, public learning pages, and selected country or city manufacturer pages. Creating an enquiry, seeing matched results, messaging, proposals, and dashboard work require an account. | Not yet reviewed at this level. |
| Free-account boundary | 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. | Not yet reviewed at this level. |
| Payment boundary | 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. | Not yet reviewed at this level. |
| Cancellation or exit | 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. | Not yet reviewed at this level. |
| 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. | 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. | Not yet reviewed at this level. |
| 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. | 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. | 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. |
