Fold the paper diagonally, and then fold the triangle in half. Unfold both creases.

Fold the form in half to make a rectangle.

Push the folded sides down to meet each other, flatten the form out to make a triangle.

Lift the top flap and fold it up so that the point meets the top point of the triangle. Do this on the other side too, then turn the form over and do the same to other side.

Lift the top flap at the side and fold the point into the center. Do this to the other side too. Turn the form over and repeat on the other side.

Fold the top flap down and fold it back onto itself. Tuck this neat folded triangle into the little pocket of the flap of the previous fold. Do the same to the other side and turn the form over.

Repeat on this side too.

Lift the top flap and fold it over the form, this gives you a flat side on which to draw a pumpkin face. You will notice there is a hole in the point at the top of the pumpkin. This way is up.

Carefully blow in the hole at the top of the pumpkin, the pumpkin will pop up to be a 3D origami form.
