So I decided to use an old guitar laying around my house and upcycle it into a shelve. What I did was remove the face of the guitar and put two shelves inside and then hung it up on my wall. It's a fairly simple project but I think it's creative and unique as well.
You will need:
an acoustic guitar
wood quarter to a half inch thick
drill, screws, wood glue, chisel or screw driver, clamps
