I just read about a new method where you don't need the freezer paper. You trace the design on the WRONG side of your foundation. You then cut a piece of fabric large enough to add 1/4" to the part you are going to applique and baste it on carefully following the lines traced on the back using a LARGE needle. You then turn your fabric to the right side trim to 1/4" around the basting and remove the basting a little at a time as you applique. The needle marks from using the large needle gives you a guide to turn the fabric under.
I haven't tried it but sounds like a foolproof and easier method to me.
