Design & Grade Sewing Patterns On Your Terms

PatternSoft consolidates pattern design into a single desktop workspace: a local pattern repository, parametric generation powered by FreeSewing, and a visual canvas editor for drawing pieces and applying size grading - with everything stored on your own machine.
