Embroidermodder 2 is a free, cross-platform GUI for viewing, editing,
and converting embroidery files. Still in alpha but the vision is
complete: a free embroidery editor for every platform.
Ink/Stitch is the only open-source embroidery digitizing platform that
rivals commercial tools. Inkscape extension. Full satin, fill, lettering,
auto-column. This is the design tool every artisan deserves.
