You don't have to applique to use applique scissors. Since I like to make bags, I use applique scissors to trim the batting or fusible fleece close the the stitching. The large flange of the scissors help to keep the fabric below it out of the way so you don't cut into your fabric. It makes cutting the fleece so much easier.

This is how the applique scissors look when closed.
