How about the Disappearing Hourglass from Missouri Star Quilt Co. I was looking at it myself and I may try it with a layer cake I have. Just a word of warning, if you use all of the 42 squares, you will have a HUGH quilt. I just made the disappearing pinwheel 5 quilt and ended up using only 30 of the squares and it still came out (with a 2" and a 4" border) to 88 x 69. But I think it would showcase the fabric.
