Seamvault: Fabric Studio

Seamvault is a private sewing studio ledger for people who want fabric stash, pattern requirements, measurements, notions, and project queues together. Record fabric length, width, fiber, stretch, prewash status, source, pattern pairing, and project intent. The workbench checks whether a selected fabric can cover a pattern requirement with shrinkage allowance and layout reserve. A bundled reference library covers stash discipline, measurement notes, cutting prep, and project handoff habits.
