Its the name of the book. The measurements a little strange. None of the blocks are the same size. some of the cuts are like 4 1/4 and 3 7/8 - Each block take 1/8 yard of assorted colors. There is a tool that I am using at the LQS for two of the blocks. Its an expensive tool...The Tri-Rec tools which makes the fat and skinny triangles. I am forgoing the outside borders and going to use my die cutter to make a triangle border. I was looking at the one in the book and to me...it will take forever. This is an interesting quilt but don't think I would do it if not for the class.
