The gray is the obvious choice.

Thank you ladies! I feel so encouraged with the kind remarks. And I like both the idea of piano keys or prairie points. It may take me awhile, but I will post the finished project eventually.

great idea

After checking out the amount of materials I still have, I've decided to do the piano key border. Is there a "standard" length or width for piano keys or should it be relative to the size of the quilt or quilt blocks??
