Maybe I should explain. I dont stitch through the freezer paper. I only use it as a guide for my stitching.
For instance, this weekend i cut out butterflies and pinned them to my quilt. (I could have just as easily cut the butterflies out of freezzer paper and ironed them on.) I quilted around each indivdual butterfly (not through the paper if I could help it) then meandered my way over to the next butterfly and repeat.
I'm not using the freezer paper for an overall design. For that, I agree that a lighter paper would be better.
