Black and White Left Overs

I had 16 left over black and white and red blocks from a yet to be put together quilt.  In trying to decide what to do with them without making any additional blocks, I pieced them into groups of four.

Then I was wondering about sashing etc.  Plan black just didn't work so added the red corner stores.  I like this much better.  

So far the quilt measures about 42 inches square.  Trying to decide on one wide border, multiple borders or maybe something pieced like a piano key.    Think I will just have to leave it on the design wall for a bit of aging before I decide.
