From a bunch of yarn balls you can make a super easy and cute wreath for this Halloween. You won’t even need a glue to make these balls. A bunch of Sytrofoam balls and yarn in 3 colors are only things you need. Although to fix them on a wire wreath you’ll need a hot glue gun and sticks. With them you can glue several layers of balls on the wire wreath and your Halloween wreath is done.
