||Using your ruler measure and draw two equal size squares on two different
colours of paper.

||Using the ruler, draw two diagonal lines across each square so that they
cross in the middle. Cut 2/3 of the way on each line towards the centre.
||Holding the squares of paper together, bend the paper back along each
cut line toward the center. Hold the corners with your fingers until you
have all four corners folded into the center.
||Push a pin through the centre making sure it goes through all four corners.
Then slip a small bead on the back.
||Push the pin into the eraser of a pencil or the doweling.
||Blow on your windmill and watch it spin!
