Thanks everyone. This is sure a fun project.
Jill, my last round is jaba's chain. I noticed that if the sides will take an even number of blocks the corners turn out the same, as in my quilt. If the side take an uneven number of blocks the corners will be different. My quilt took an uneven number, so to keep the corners the same, I added that red block in the center of each side. That made the chain turn direction. So the purpose of the middle block was to keep the corners the same but I ended up liking the way it looked too.
