Ok, a tip for the freezer paper method.
Fold the edges around the circle of fr**eezer paper template. You need to clip the seam allowance almost to the fold line. Don't go past the fold line crease into the body of the circle. The snips in the seam allowance allow the seam allowance to spread out and stack on top of one another. It should eliminate the wrinkles.
A technique that may be a solution for you. Just incorporate using the circles.
