I didn't have any foam cones around the house, so I folded a piece of cardstock in a way that made a cone and cut the bottom off to make it straight. Then I took a piece of sheet music, cut it into strips of about 1 inch wide. Cut little notched down the whole bottom of the strips. Then all you have to do is glue/tape them around the paper cone. Towards the top you'll have to start cutting the strips of paper shorter.
