Cut 6 squares of any measure. Take one and fold it on 4
Put it vertically and bring the four corners to the fold. Then fold each side to the center.
Fold the strip in four as the image. Then introduce one side into the other through the opening.
Do this process with the other 5 squares and you must have 6 triangles. Paste them all together to make a hexagon.
To make the base take a piece of box cardboard and make a hexagon then paste it. If you want you can cover it with cotact paper or thick tape.
