I made this as a surprise birthday gift for my Grandma. (Happy birthday Grandma!) Made entirely out of paper, except for the strings in the inside of the piano. I painted the black parts so they were super black. (before they looked a dark grey) Also, the cover folds down over the keys, you can adjust the angle of the music stand or collapse it completely, and the top can close, has an extra part that can fold over the music stand when closed, and the arm can be placed at two different heights to keep the top open.
Do they have a paper craft for that piano in Super Mario 64 (DS) in the haunted house where the piano has jaws and tries to eat you if you get too close...?
