yes freezer paper and follow the direction just the way I wrote it. Cut a strip 11 3/8 out of freezer paper and cut a 60d angle, turn and measure 13 3/8 from the point and cut the other 60d angle and then start ruling like the previous instruction say. You're going to start ruling from the edge of the diamond up. Make sure to include the 1/4 seam allowance on the first four lines and then follow the instruction for the rest.
