Before you buy I would contact the company and inquire if their product will fit your Gammill. Also check out youtube to see if there are any videos of Quilt Magician that you can watch. I'm not familiar with it but have seen Quilt Motion and it's wonderful. Also have my first bed size quilt on my bed right now and it was quilted on a Gammill with Statler Stitcher. So if Quilt Magician is like either of these programs, it should be wonderful!
