I read this instruction in a book about machine satin stitch applique and it has worked for me. Apply Wonder Under to the back of your applique. Leave the paper on while you do your satin stitching. After the stitching is finished, when you are in the sandwiching part of your quilt, then pull the paper off and let the light adhesive from the Wonder Under help with your basting. The Wonder Under keeps the fabric from stretching, and the paper makes the quiding of the fabric around the curves, etc. go marvelously easy. I haven't had one bit of a problem since I started using this instruction and I have been doing some very intricate curvy details.
