This is another fun Pinwheel idea for summer! I made a lot and filled a large bowl with them! But you could string them, put them on sticks, or use them around the tables on your next summer gathering.
For this project, I recommend using double sided heavy paper. I used a 12 x 12 pad of scrapbook paper with interesting designs that go together.
For a 12×12 sheet, you can make 4 templates and 2 pinwheels. Each pinwheel uses 2 template fans.
