I want to share my method with you because it is so simple, fast and has a wonderful finish. If you're not crazy about machine appliqué, this method might change the way you feel about it.
In a 2-cup measuring cup, mix 1 teaspoon of cornstarch with
Using a cotton 2-ply fine embroidery thread that matches your appliqué shape and a 60/8 needle in your sewing machine, sew the shape to your background very close to the edge with a straight stitch. Start sewing with a very short stitch to anchor the shape and gradually increase the stitch length as you go around. As you get close to where you started sewing, decrease to a shorter stitch and remove from your sewing machine and cut the threads.
