I would definitely use the music fabric in a disappearing 9 patch. I would use the instrument fabric as the corners that remain uncut, the dots as the center squares and the wavey as the remaining 4 squares. I think that would make an awesome quilt!!!
Where did you find this fabric? I absolutely loveeeeee it. We own a music store and I'd love to make DH a quilt like this. Hugs and smiles, wildlinda
