Tetragami Kids

Tetragami is an art of folding I came across lately, due to my aunt sending some of the special paper.  Tetragami is a fun version of origami based on Tetrahedrons.  There are many things to make and fold using Tetragami.  Some of the basic shapes are Tetrahedrons, Double Tetrahedrons, Octahedrons, and Double Octahedrons.

Here is a site that has the basic shapes:
