The petal is a very simple example of proper origami (just paper folding with no cutting or gluing), but I admit I've cheated a bit in putting the petals together into a star.
This is one of the simplest examples of an origami project you can make -- which makes it a perfect introduction to the artform for early grade school children! My thirteen year old still loves making them as they turn out very pretty.
