Believe it or not, these DIY Mickey Mouse cardboard heads are made out of these simple cardboard cake boards. All you need are some cake boards, black spray paint, and some scrap little pieces of wire. You can make them in a few different sizes if you get a set like this.
Step One: Spray paint the cardboard cake boards black.
Step Two: Use the wire to attach the small boards (ears) to the larger boards (Mickey head). You can also use some hot glue along with the wire if it doesn’t seem to be holding very well.
Step Three: Hang them up with some tape on the walls.
