I've got PE-Design, which theoretically lets me convert from other formats and design my own stuff, but I haven't taken the time to sit down and learn it yet.

On the other hand, I'm not adverse to hearing about other, easier patterns! Gee, when I got Poohcifer I figured the 4x4 embroidery pattern was on its way out, but it looks like there are billllyuns and billllyuns of options.
