Fold the small triangular flaps over on both sides.
Bring the middle section up over those flaps.
Turn it over so that you can see two small triangles on either end.

Bring the side so that there is a square with a diagonal showing on the end.

Crease to make a crisp fold.

Open up and repeat on the other side.
