This ChiaoGoo yarn swift is a handy tool for winding a hank of yarn into a ball. Place a hank of yarn on the pegs, adjust the pegs in order to achieve the desired tension and start winding. Winding can be done by hand or in combination with a yarn winder. The non-skid pads on the bottom prevent the swift from moving while you work with it. After use, this yarn swift is easy to take apart and store.
