The above link has been the lifesaving trick for me to learn to paper piece
efficiently and without any "hold it up to the light" problems. I have
taught it at our guild meeting for a techniques day and teach it to friends
every chance I get. You will figure out how to cover odd shaped pattern
pieces as well as knowing which way a stripe (or grain) will lie after the
piece is flipped. I'd love to know if anyone else has learned this
technique from the website. I admit that I follow directions pretty well,
but I think the directions are so well written, almost anyone can learn the
trick. Happy paper foundation piecing!
