necklace part 2

    I finished the elements I wanted to make for my necklace--1 big and 6 small.  Now how to join them.  My plan was to just make ladder-like circles of beads to join the elements.  I made one and joined the big structure to the bottom left one that way. But I didn't like it so much.  After some playing around I realized that the corners of the big piece had an angled tube that was at right angles to  the tube at the corner of a small link.  So they could be opposite edges of a tetrahedron.  I did that at bottom right, and it makes a much cleaner connection.  It will also work between small elements, so I think that's what I'm going with.
   Actually something just occurred to me as I write this.  The loops I originally planned, because they're less structured, would allow the links at the back to lie next to your neck.  I think the tets will force the whole necklace more or less into a plane, which means the back links will tend to stand up.  Double tets at each join would give more flexibility, but would (I think) only work if the tubes on the adjoining links were parallel, not at right angles.  Hmmm.
