Really cute, easy to make, Flat Paper Pinwheels
Really SUPER easy. Anyone can do it :)
Get a normal piece of paper and cut it down to a piece of paper that is an equal sided square, like the pieces of paper you would use for Origami.
Put a dot in the center of the paper and decorate one side or both sides for a cool looking pinwheel.
From each corner, cut halfway down to the pinwheel. You will have four triangles. Fold the right corner of each triangle and press to flatten. Tape or Staple the center and you have a new flat pinwheel!
