Store description excerpt

SeamShift turns body measurements and finished-garment measurements into clear, repeatable pattern-alteration worksheets. Choose an alteration, see the exact formula and assumptions, follow a vector diagram, and keep the result with your sewing project. Includes full- and small-bust worksheets, waist-to-hip blending, length changes, shoulder width and a user-entered sway-back worksheet. Export PDF worksheets and CSV calculations, or create a validated JSON backup. SeamShift does not create copyrighted patterns and does not promise a perfect fit: always follow the pattern instructions and sew a test garment before cutting final fabric. No account, ads, tracking or developer server. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://viralcrew.de/apps/seamshift/privacy
