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
Cut away the fabric around the shape leaving a 1/4" seam allowance.
Apply the starch to the ¼” seam allowance with a small paint brush.
Using a mini iron and an awl, press the seam allowance towards the freezer paper.
Once the shape has cooled, remove the freezer paper template and if needed finger press the seam allowance back into place.
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.
