The benefit of the freezer paper/fold method is that the ironing hold the paper to the fabric. You then fold the freezer paper back along the stitching line, trim the seam allowance to 1/4 inch on the first piece and sew the second piece to the first just outside the fold. You then iron out the second piece and fuse the freezer paper pattern over the second piece, fold back, trim, add 3rd piece and sew on....
After the block is finished, the whole freezer paper pattern piece is peeled off and can be used again until it stops sticking when ironed.
