How to fold an origami piranha

A kite left open, so the body is deep. Pleat a step behind the head, snip the mouth so the pointed lower jaw juts out, round the body and fork the tail.

You need: 1 square sheet (15 cm), dark grey on one side and white on the other, scissors, a white pen and a black pen. Hard, 10 steps, about 20 minutes.

Steps

  1. Fold in half. Grey side up, fold the top corner down to the bottom corner.
  2. And open it. Unfold it again, so you have a sharp crease across the middle.
  3. Make a kite. Fold the two right-hand edges behind to meet along the middle crease, so the front stays grey.
  4. Fold the head over. Fold the left part over to the right on an upright crease 7 cm from the left corner.
  5. Pleat it back. Fold it back to the left on a crease 6 mm to the right, so a step stands behind the head.
  6. Round the back. Fold the top and bottom corners behind on gentle slants, the back higher than the belly.
  7. Snip the mouth. Snip along the middle crease from the snout corner, 3 cm in, so the upper and lower jaws come apart.
  8. Underbite. Fold just the upper jaw behind on a steep slant from the end of the snip. The pointed lower jaw now juts out in front.
  9. Snip the tail. Snip along the middle crease from the tail tip, about 6 cm, so the tail splits into two halves.
  10. Fork the tail. Fold each half of the tail out on a slant from the end of the snip, one up and one down, so the tail is a wide fork.

Chomp!

Draw a big eye, a mouth line from the chin and a row of white pointed teeth along it.
