Crease Pattern Origami. In recent years, a new form of written instruction has become common within the modern art of origami: A crease pattern is basically just an origami model that has been unfolded and shows all the creases on the original flat piece of paper.

Crease pattern represents a base. Refold the model from the new paper using the crease pattern plus using the old unfolded model as reference. Crease patterns (cps) are a method of describing models through the final set of creases the model uses rather than by individual folding steps.
