Know before usingA 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.It is one curator's intentionally selective, off-Ravelry-oriented database, inventories change, and paid supporters can receive rotating priority placement; verify availability, fibre claims, shipping, and terms directly.The workflow is not a contract or quality certification; local legal duties and technical review may still apply.Patternmaking knowledge, controlled measurement files, production conventions, and sewn fit testing are still required. The software does not validate body measurements, ease, balance, grading rules, fabric behavior, construction, or product fit. The project currently labels its user wiki manual as needing updates, so confirm current commands and file behavior against the installed release and active support channels.

Source and review
What the source establishesSewport'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.The individually researched database offers free listings and sortable yarn, fibre, designer, editor, accessory, and location views; the EU page spans multiple countries and direct seller profiles.The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface.The maintained Seamly2D repository identifies the application as GPLv3+ open-source patternmaking software for Windows, macOS, and Linux. It reads multi-size measurement files for standardized sizes and individual measurement files for custom-fit work, publishes downloadable builds and releases, and links an active website and user forum.
