make your own longstitch pattern?

[mad-persephone.livejournal.com]

HI there everyone.

sorry if this has been asked before, but does anyone know how to make their own longstitch patterns, or know of some software I can buy to do this? I've googled and can't find anything, and I have PC Stitch but there is very little on that in the longstitch pattern way. If any of you can point me in the direction of a tutorial, method or software I would be most grateful

thanks
