I sew giant 6' tall Santa Hats, and I need and equally huge sized puff ball. So I made a simple design to help make these puff balls. Print in place, glue the dowels in and snap it together. You just need to start wrapping you choice of yarn around the posts. I do recommend every 10-25 passes to wrap and tie off a separate piece if yarn in the middle nice and tight. Once you get your happy size, just lift off one side and cut the yarn down the side. Then repeat on the other side. Now you have and awesome puff ball.
