Easy origami. Big origami

Origami is the Japanese art of folding paper. It is originally from Japan, also known as origami. It  can be defined as an educational art, which develops creativity, calm, and patience in those who practice it.
Starting from an initial base (rectangles, triangles or other shapes) really beautiful figures are obtained. The only rule is that everything has to be done by folding the paper and in one piece, without breaking or gluing it.
