Bag.
Fold a square sheet of paper diagonally like this, to form two triangles (drawing a). Fold the side vertices of triangles A and B like this, to touch the opposite side of this triangle (drawing b, c). Two vertices C, C’ bend down (drawing c, d). Depending on the material, what are you going to make this bag out of?, you can use it for different purposes. If you make it from tracing paper, it can be used as a cup for drinks during a trip or trip. Made of paper or cardboard, you can use it to hide your treasures (rocks, amber, shells or other trinkets). Turned upside down, after being decorated with a feather or other decorative element, it can be a carnival hat.
