Materials –
Small shoe box
Paper towel roll
Box cutter knife
Rubberbands

Trace a circle on top of the shoe box and cut it out with the knife. Trace the paper towel roll in the middle of one of the sides of the shoe box and cut that circle out as well then place the roll in through that cut. Place rubber bands on the top of the shoe box as if they were the guitar cords. Lastly place two stronger rubber bands on the outer part of the shoe box so it can keep it in place, as closed. I painted the box and roll before putting the guitar together.
