I have been thinking about making pinwheels and put them in a vase as a centerpiece for my parents upcoming anniversary party. I am not sure what you call the center of the pinwheel that goes thru the paper and attaches to the handle. But does anyone know where I can purchase that or how I can make it? I have read on line that you can use a straw with an eraser, but I wanted it to be a little bit better quality than a plastic straw. I want it to stay on well, but I don't really care if it turns. Any thought?
