While at the Quilt Fest in Jacksonville, I watched a demo on a tool called the Twister Tool. You use it to make easy pinwheels. The tool is available in two sizes. One size is large for layer cakes and one size is small for charm squares. It is so easy to do I photographed the demo! I purchased the large size to use with layer cakes (10" squares) and went online to order the smaller size to use with charm squares.
