I have used the mylar before and works great, but I don't always have it when I need it. Now when I make an applique pattern, I print out the piece needed making sure it printed at the same size. Cut around shape leaving extra outside of line. Glue to a piece of cardboard from coke, cereal, cracker, etc box. Cut out shape on the line. Put shape on back of fabric. In your case, the fabric is already cut to shape with turn allowance. Position cardboard shape, you can use a light dab of glue stick to hold. Spray starch in a water bottle cap, qtip starch on turn allowance, and iron turn-edge over cardboard. Hold iron for a couple seconds to dry and set. Don't scorch fabric. Let it cool and remove cardboard. Your edge will be set and smooth (if you cut the curve without any jagged parts. Cut slowly and with blades closest to handle.) Sorry for long instructions. You can see in picture what I have done. [ATTACH=CONFIG]575537[/ATTACH]
I don't have good luck with freezer paper, as the layers won't stay together, no matter how hot the iron is, and the edges bend, lap over, and distort after I use them a few times.
