Zigzag beaded Byzantine

The Zigzag beading technique combines two sizes of round beads set on flexible beading wire that travels through the base Byzantine chain. This embellishment is available in a variety of color choices of combining, 6mm amethyst with 3mm quartz, or both bead sizes in royal-blue lapis lazuli, or black onyx set on flexible beading wire and secured with crimp beads.

I have a tutorial online at PBS's beads, baubles, and jewels.
