The Tracing Wheel with serrated edges is used to transfer markings from your pattern to your fabric, with no tracing paper required. To use, place your pattern onto your fabric, and trace over the markings with the Tracing Wheel to make perforated marks on your fabric without damaging it. Works great with lightweight fabrics.
You can also use the Tracing Wheel to transfer your pattern to other paper, or to transfer your entire pattern onto your fabric.
