Question, is the center block 8 inches finished or unfinished?? Secondly, you want the center block to be square and then the side blocks to form a diamond around it and then a square around that, right??
If that is the case, you will be working with 60 degree angles. Much better to make the block 16 inches because the math becomes very simple. It would be a sawtooth star with the side pieces inverted.
