Yep, it's paper! The keys are cut of cardstock, holes punched, they are rounded over a dowel, then brads inserted for decoration. I used silicone glue to align the keys on two pieces of woodgrain cardstock. Finally, the whole is mounted on card covered with patterned scrapbook paper.
The hammers are created with bamboo skewers and buttons with the shanks clipped off, both glued with silicone.
