The center strips you would cut out of each of the charm squares can be used in another block. (I have shown this in the 3 sets of blocks to left of the original block.) They will be a bit narrower, but very usuable.
You could also add scraps to those secondary blocks if you wish to spice up the centers a bit, or rotate them to the outside corners.
I will add the templates for these blocks. Edited*** These will all finish at 4"
