I think this is the final layout, unless another idea jumps into my head while I stare at it.
I started another batch of blocks because I still have so many strips left. That will give me a chance to use one more layout and then I have to move on to something else.
Someone asked if I'm using a foundation for my piecing. No I rarely use foundations. I just piece, press after a couple strips, square it up about 3 times in the process of making the whole square. That keeps it from getting too stretched out of square since a lot of these strips are crooked cuts. They are all the clean up cuts from straightening the ends of a piece of fabric.
