I use freezer paper to do hand applique all of the time. It is my favorite method. I cut the freezer paper template, iron it on the back of the fabric. Cut around the template, leaving a scant 1/4 inch seam allowance. I use my needle to turn under the seam allowance and start stiching. I gives me a crisp, smooth edge to stitch. When I get about an inch from where I started, I take tweesers and loosen the freezer paper from the fabric after I have finger pressed under the seam allowance. I remove the freezer paper and continue stitching on the finger pressed line. I have taken a number of classes on hand applique but I always seem to go back to this method. I haven't done machine applique yet; but since I have a new "sewing computer", I am anxious to try it. I will most likely use some type of fusible web under the fabric when I get around to doing the machine version.
