I have used the interfacing method for applique, one a wall hanging of pansies, some quite small (and leaves) and had no problems if you use your needle to keep the interfacing under control if edging by hand. I haven't attached the pieces by machine as I enjoy hand applique best. Another thing you can do with this method is to put a small amount of filling into the piece to give a more dimensional look to you applique. I actually had never seen or heard of it and was just one of my experiments - was a bit of a let down to find others had already been doing it. L. O. L.
