Tada they are done!
Here is the grouping I finally decided on, hung up on my wall. I am so not good at mathmatics and trying to get this perfectly straight. (that's my moms job, but we just moved away from her so I had to do this on my own) So I just measured the middle three over the center of our bed and the rest I just went for it and hoped it would look ok when I took a step back to look at it. It's not perfect but I am pleased.
