My son was excited to go to school today because they were making pinwheels for a pinwheel parade. When we got to school, I saw the origami paper out and the sample pinwheel and asked the teacher about it. They are making origami pinwheels to celebrate International Day of Peace on Friday with a pinwheel parade. How fun is that?! I think I might have to make some for home. They were attaching the pinwheels using a push pin (I think) to a pencil eraser, and then the pencil becomes the stick to hold the pinwheel. Here is a tutorial that I found: Origami Pinwheel instructions from TinyShiny.com.
