Tetrahedra

I attempted chapter 2 of the modular origami polyhedra book. Managed the chain-of-4-equilateral-triangles from a square (by Lewis Simon) without too much brain-pain but failed miserably with the modular from a hexagonal piece of paper. It took long enough accurately making a hexagon from a square! Started getting quite frustrated because I couldn't make sense of either the diagrams or the instructions so in the end I screwed up my attempt and made another Sonobe cube and a tiny peace crane instead. Happiness and calm restored :)

I'll attempt the other models another day before I move on to Chapter 3: Octahedra. Yikes!
