I have been buying up 'music' fabric over the past few months but haven't seen any with piano keys. [QUOTE]
Me thinks you don't know what "piano keys" refers to. They are the strips of colored fabric surrounding the quilt, radiating outwards. There are quite a few posts in this thread that show them. I've never seen fabric with just the piano keys in black and white either, but did see a very large piano keyboard in a quilt. That one was built by the quilt-maker.
