I use freezer paper but I guess I use it differently. I lay the dull side of the freezer paper hex on the fabric hex squares, which are cut 1/4" larger on all sides, then I turn the seam allowance over the edge to the shiny side and iron it down, so it is 'stuck' only on the seam allowance. (Clear as mud so far?) I have used the same ones for several quilts now. They are easy to take out as well.
