I have great closeups of several of David's quilts, which would show the difference, but can not post without permission. When you look at edges of his pieces they are turned under applique. He does not need to fuse, nor use blanket stitch or zigzag to tie pieces down. The turned under applique provides a more natural look to edges of his subjects, while his quilting is then used to "define" the flow of the body features of the subject (the curves of petals, hills and valleys of a body, fur, feathers,etc.) I hope this makes sense.
