How to fold an origami whale tail

A triangle with its two sides folded across, one in front and one behind, so the corners pop up as flukes. The bottom point folds away for a flat sea line.

You need: 1 square sheet, 15 × 15 cm, blue-grey on one side. Easy, 4 steps, about 3 minutes.

Steps

  1. Make a triangle. White side up, like a diamond. Fold the top corner down to the bottom corner.
  2. First fluke. Fold the right side over on a crease from the bottom point to 2.5 cm right of the top edge's middle. Its corner pokes up past the top on the left.
  3. Second fluke. Fold the left side behind on the same kind of crease, 2.5 cm left of the middle. Its corner pokes up on the right, making a V.
  4. Flat sea line. Fold the bottom point behind, about 4 cm up, so the tail rises from a flat edge like the sea.

Splash!

Wave it up and down like a whale diving deep. Fold a few in different blues for a whole pod.
