Disappearing hour glass pattern
I just watched a video about a disappearing hour glass quilt from Missouri Star Quilts and she started out with 10" blocks..however I cant find the pattern anywhere that would give instructions on how to make the final block 12.5". I know after you sew the blocks then cut and sew them again its going to change the size and I was just wondering if anyone had made this block and could help me with the original size to start with? Its a VERY pretty quilt! THanks!
