I saw Legacy by Pellon at the quilt show in Des Moines. It is foundation piecing rather than paper piecing and is for like flying geese and there were several block patterns also. You do tear it away but it seemed to pull away very nicely without pulling the stitches. Also they had a compass block quilt on display that 5 or 6 different quilters had completed and it was amazing how accurate and precise all the blocks were. None of this 1/4 inch seam problem. Just stitched on the foundation. I found it amazing for the blocks that were already printed. I think each made a 12" block and you decided how to put it together. Of course, none of the sets had copyrighted patterns like Carol Doak's or Niemeyer's. I asked if it was sold by the yard and she said the product requires a special printer so you can't buy it and just use for something you copy.
