OMGosh, what an Awesome quilt pattern!!! I like your piano keys, and then could you put the lilac fabric as a border outside of the piano keys as a final frame? Or quite honestly, you could finish it just like it is: piano keys on 2 sides and solid on 2 sides, and a darker solid purple for the binding. This is a great quilt, and I see there is another partner pattern also. WOW!
