Start with a square piece of paper.

Turn the paper 45 degrees,
fold corner to corner, then unfold.

Turn the paper 90 degrees
fold corner to corner, then unfold.

Fold the top point into the center.

Fold the bottom point to the top of the pentagon.

Fold the right side up into the middle,
so that the point that was on the
right side is now at the top of the object.

Repeat the previous fold for the left
side of the object.

Fold in the triangles at the top and sides under
the shape to make the figure more rounded.
