I gathered up most of our patriotic merchandise & made up this display earlier this month. See the pinwheels? They're two 6" squares of fabric fused together with a stiff fusible web. Then you cut in about 3" from each corner into the middle. Bring the tip of every other corner into the middle of the square & glue - you have pinwheels!
I put mine on my good chopsticks but you should probably pin yours into a straw and then they will turn. I couldn't find straws and I wanted them in the display so the chopsticks are now histrory for eating utensils!
