Paper Boats
Fig. 2
If the cocked hat is held in the middle of each side and pulled out into a square, and the two sides are then bent back to make another cocked hat (but of course much smaller); and then, if this cocked hat is also pulled out into a square, it will look like Fig. 2. If the sides A and A are held between the finger and thumb and pulled out, a paper boat will be the result, as in Fig. 3.
