Stop using your thumb or broom stick to wind a center-pull ball of yarn! ChiaoGoo wooden Nostepinne or "Nest Stick" (an old Norwegian hand tool) can do the job for you. It is approximately 11 inches long (long enough to wind a large ball of worsted or even chunky yarn) and has a nice smooth finish, but not too smooth where the yarn will just slip around when starting your ball. Comes with a loop through the handle to hang on a peg. Instructions included.
