Paper folding, or origami in Japanese, is a traditional craft that has been enjoyed by both children and adults for hundreds of years. An origami is typically made with a square piece of paper and no additional tools. A series of folds can transform a flat piece of square paper into an everyday object such as a bird, a boat, or a flower. Aligning vertices or edges makes a crease, and as new creases are made, they and their intersections become additional matching targets used to create new folds.
