Is there a reason for using freezer paper? I paper piece and simply use regular printer paper (20 lb weight). It's cheap enough and much easier to remove than f.p. A tip I learned from my quilt teacher, if you spritz the paper a little before tearing paper off, it comes out much easier. It can be a little messy because it's wet but easier on the hands. Also, I use 1.5 mm stitch length which perforates the paper well. This works for me anyway.
The quilt in my avatar was paper-pieced....a lot of it.
