Cut out the biggest square
Cut out the biggest square from an A-4 size paper. Fold the mid-line. Then fold through one corner while placing the other corner on the mid-line. This way you will fold 60-degree angles. Continue till the whole paper has a triangular grid. Now eliminate a few by tucking and folding. Make a beautiful PYRAMID or a self-locked TETRAHEDRON. The challenge is to fold an OCTAHEDRON?
