   Read the three figures left to right. Crease a horizontal midline; prepare the collapse along that line. Crease both diagonals as shown.

   Collapse to a double-layer triangle. Fold the two front lower corners up to the top point.

   The left figure shows the two lifted corners. Turn the model over; position the triangle with its point facing down, as on the right.

   Lift that downward point up past the long top edge. Let the paper curve; do not force the entire model flat. The right figure is the result.

   Fold the small projecting tip over the top edge to the back, locking the layers. The right figure shows the locked tip.
