After the hourglass shape is sewn together the block is 12.5-12.75”. The instructions are to cut 2” from the center. After I finish cutting, the only section that is actually 4” is the four patch, all of the other sections I have to square up and trim approximately 1/4”. Having said that, I still like the pattern. I played around with the layout of the block and decided to change it. Here is the new block, I love the secondary pattern it creates.
