There's software called Embrilliance Essentials by BriTon Leap, Inc that lets you save the tack down step of an applique digitized design as a Silhouette file. You open the design in EE and save the first step as a silhouette file. You take that file and open it up on the silhouette and it will cut out the perfect piece of material for stitching it out. When you buy the program and load it on your PC or Mac there is a free update to do the applique part. It is a program that lets you combine, overlap, convert or split designs. It costs about $150 but is easy to use. If you are embroidering a quilt with a lot a applique designs it will make things go faster for sure. You can have it on more than one computer at a time. There are not many programs that work on the Mac.
