There's also symetry...each one has a center bead (or in the case above right, split evenly in the center) and then each bead is mirrored on either side
And then I wondered what it would look like if I stopped doing that, just once...obviously I didn't use several different shapes, I didn't have anything else like this bead. I love these, they're practically luminescent, I poured them out on my plate and thought 'they look kinda cool there in no particular order' and then I had a new style, lol. no order to the shape, size, number of beads in a 'set', even the lenght of chain between the sets is out of uniform...and I love it!! I failed a little with the bracelet, it almost looks orderly, lol.
