I know it's nothing special and it's not exactly perfect.. but.. It worked! It's an original embroidery design, made on free software, and embroidered by my machine! I used the Inkscape plugin available here along with Wilcom's TrueSizer.. And I made an original design.
I only just got it to work right before dinner, so I haven't gotten to play with it much.. it kept giving me errors, and then I started kinda haphazardly putting python files I thought it needed into the Inkscape extensions directory.. and then suddenly, it worked!
