I hand applique with freezer paper and a round wooden toothpick. I keep the toothpick in my mouth to keep it wet, then use it to turn the 1/4" allowance as I go along. Keeping the toothpick wet allows it to "pull" the fabric around behind the paper. It's the fastest and cheapest method for me....as someone said, you can reuse the freezer paper 100s of times.
