First take a stiff black paper and fold it diagonally and then open to form a crease. Repeat on the other side.
Cut off the remaining strip. Using scissor cut along the lines from each corner nearly to the center.
Bend each alternate corner to the center and secure each end with a map pin.
You can see that it is easier to pin the ends when the sheet is flat.
Push the pin through the center of the windmill to the back and let it pass through a short bamboo cane. You can use a small piece of cork to cover the sharp end or bend the sharp end slightly to prevent it from protruding.
Now we have finished making our Wind Mill !
