Almost forgot a tip! If you decide on doing the piano key border, you'll need to SID on each key in order for it to lay flat (from inner border to outside edge); otherwise it will wave if you do a vine motif on your top quilting! I did a vine and I knew it would wave and that's alright- I wanted to give the keys some movement - as if someone were playing them!
