Take a sheet of paper and fold it in half once. Then fold the two halves in half again. Now unfold the sheet again and press the upper half down so that it lies on the fold in the lower part. Now it’s time to draw. Draw the outline of an animal or a head on the upper half and the lower half. The mouth should always be at the top and bottom of the fold. Now you can pull the sheet apart again. Now draw the wide open mouth and the rest of the animal. Then fold the whole thing up again like before. If unsuspecting people unfold the sheet now, they may get quite a fright….
