This is four-petals version of origami morning glory. The paper used is a one-sided origami paper. This version of morning glory starts from square-base.

This five-petals version simulates the real morning glory. It is a little difficult to fold compare to the four-petals one. But if you master the four-petals one, then you will have no problem in folding this version. The paper used here is a two-side origami paper.
