I don't know how much you have and how big you want the quilt.
But, honestly, I really, really like that WVblock fabric.
If you cut it carefully, you can always use the leftover squares mixed in with whatever leftovers you have and put it on the back.
So what if they're not perfect squares with the pattern. The colors and logos will still bring the theme over to the back.
Will that give you enough fabric to make the size you want?
