If you have a preference for your own fusible, draw your appliqué shapes as normal, but then cut approx ¼" INSIDE your line, and you will be left with a spider web of your shape. Fuse this down onto your appliqué fabric & and then cut on the line. You will be left with your appliqué shape that has only fusible on the edge. Fuse this piece onto your background (in your case a pieced top) Then satin stitch or buttonhole stitch the edges. (I also use a stabilizer behind the background piece) HTH
Pat Sloan uses this technique, there may be a you tube on it.
