I don't like the raw edge applique with fusible, because the fused pieces get hard and inflexible. I much prefer sewing the pieces to interfacing and turning. If you use 1 side fusible interfacing, be sure the fusible side is facing the right side of the fabric when you sew them together (do not iron at this point). Turn and remove the center of the interfacing, then attach to the quilt.
I've never used the dryer sheets for this because I've never used them in the dryer (I'm allergic to all brands I've seen).
