I was in Joann's the other day and the woman in the sewing machine dept. was making quilt blocks,using 1 1/2" strips and sewing 1/2" seams at one end and reducing the seam allowance down to 1/4" at the other end of the block. When I asked her about it, she showed me the quilting mag that called it fandangles (I think). Really cool technique! I like what you are doing, it's going to be a beautiful quilt!
