Torus necklace

This is the first actual piece of jewelry I've made from my torus structures. I like it because it's the first time I've varied from the actual structures I found in the beaded molecules blog. The 6-sided torus is basically taken from the blog. It's the one that uses octagons in the middle and squares on the outside, and it wants to be a hexagon type torus,i.e. the structure creates a 60 degree angle between the sides. However I found I could force it into a 90 degree bend, to create the square torus. As a general matter, I find I like forcing my beaded structures into shapes that aren't exactly what they want to do, because the forcing creates a stiffer structure. An example would be a tetrahedron created using right angle weave. It makes a somewhat rounded, but stiffer, tetrahedron.
When I tried to force the structure even farther, into a 120 degree bend to make the triangular torus in the middle, it just wouldn't go. I simply didn't have enough beads in the outer part of the torus to accomodate the greater diameter. So I changed the squares (4-bead circles) to rectangles (6-bead ovals) and then I could make it work.
