Find a piece of sheet music that you are allowed to cut up!
Cut each line of music. I used a paper cutter so it wasn't too tedious. Make sure you don't have too much blank space on the strips.
Cut those long strips in half so you have a bunch of short strips.
Get the balls you're going to cover out. This will not come off once you put it on, so make sure you're not covering a ball that you really like.
Take the hanger piece out of the ball. Getting the Mod Podge on this would look really tacky. Literally! ;)
Paint part of the ball with Mod Podge.
Place one of the strips on the ball.
Paint a layer of Mod Podge over it.
Put another strip on and repeat.
Place upside down on the hanger opening to dry.
After it's dried, put the hanger back in.
