Jill, I guess if it were me, I'd put the same squares in the corners because they look a little empty. But that would probably change with the next round. Those blocks look very time consuming to make but are so pretty.
Mamahen, Looks great! That little strip of blue really worked! And what pretty fabrics. I also like some of the very narrow strips you used. They provide a border without being loud. I didn't even notice them until the close-ups.
