Raw edge applique is created by NOT USING FUSIBLE WEB to apply your applique to the foundation, OR cutting the fusible web smaller all around so that the edge of the fabric can "fray" and leave a fuzzy raggedy look around the edge. You would stitch approx. 1/4 inch in from the edge so that the edge of the fabric IS NOT attached to the foundation. Is that clearer? It makes for a creative way to applique and create texture, especially around flower edges. It's sort of a 3D look.
