I do my applique almost the same way, although I do not have an Accuquilt. I use mylar, cut out the shape, and use that to cut the fabric. I then put the shape over the fabric, starch the edges to be turned with a small paintbrush, and use the iron to turn the edges. Makes the edges smooth as well as easier and quicker to applique to the block. You won't get bumps if you cut slowly and don't stop the cut on the curve. You have to turn the mylar as you cut with the scissors. It took me a couple trys before I did it right. Kept wanting to let the scissors do the driving!
