How can I create a 3D star origami using simple folding techniques?

To create a 3D star origami using simple folding techniques, follow these steps: Start with a square piece of paper, fold it in half diagonally both ways to create creases, then fold the corners to the center point. Next, fold the edges to the center line, flip the paper over, and fold the corners to the center again. Finally, fold the flaps outwards to create the 3D star shape.
