I'm trying to upload some images of some of the donut (technically torus) structures I've built based on the incredible carbon nanotube stuff in thebeadedmolecules.blogspot.com. The larger picture used seed beads, and to create more open structure I used 2 beads for each edge. It's around 3" in diameter. Looking through all the structures in the blog, I've been trying various versions. For jewelry I'm trying to keep the minor diameter (ie the diameter of the curved tube, not of the whole torus) relatively small so the piece isn't too terribly thick. Also I want the very outermost part of be a row of shapes,not a border between rows of shapes. That way, when I get beyond single toruses (tori?) I can build a structure to link together a series of them. The other picis of various structures using 4 mm stone beads. I sort of like the blue one on the left best, as it's quite firm and not too thick, but it doesn't have a bead circle on the outer rim. If I connect to a bead circle it will slightly on the back of the torus. So I'm still playing.
