Traditional Origami Bases

Every origami model in its essence has a base. No matter how complicated or simple a model is, the base is always an initial step.

Basically, wherever you have a polygon that forms a flap and it is located on the paper edge, you can use Elias stretch manoeuvre to collapse that polygon.
