Coxeter Beaded Bead in Aqua

Here's the latest piece of my bead mat, a Coxeter Bead. It's a little over an inch wide, quite hollow, and it has big holes for stringing it on cord. The symmetry of this piece makes me think of a virus.

The dominant color is the aqua bugles, and then I added matte blue half tila beads to soften the bright aqua.  The tiny drop beads inside the circles came from a mixed box of beads, and I separated the colors when I wove them into the beaded bead. 

If you'd like to learn to make your own, you're in luck because I wrote a tutorial that explains how to weave a Coxeter Bead.  Thanks for looking!
