I commend Peg for this video. I learned something new today! (grin). However on the block with the folded triangles in 4 corners it appears to me that you will be losing the points when you join those blocks to other blocks. Perhaps a folded square that is slightly larger would provide the overlap that is needed for the seam allowance. I also agree with some that this is a waste of fabric. Good ideas for quick quilts though.
