PatternFoundry

Sewing patterns that fit you.

PatternFoundry is coming: free software to draft sewing patterns from your own measurements, grade them across sizes, and print them at true scale on a home printer, at a copy shop or on a projector.

There will be a free hosted version that runs in your browser, with nothing to install. The AI features will need you to be signed in with a free Foundry Account.

What it will do

Measurements

Drafted for your body

Enter your measurements once; change one and the pattern redraws itself.

Pattern pieces

Seam allowance, notches, grainlines

Everything a sewable pattern needs, added for you and kept right as you edit.

Printing

True scale, every time

Tiled home-printer pages with alignment marks and a test square, copy-shop sheets and projector mode.
