Clever idea. Any block could be framed that way. Hmmmm......
As Prism99 stated, but there's 5 blocks , in 5 rows,and some of the blocks look like they were cut in 1/4's, with HST's on opposite sides of the block, some of the other blocks are just solid. I would draw a draft on graft paper and just figure the math. Good Luck. I love the layout.
