Jacob's DNA Ladder (aka Captive Inverted Round)

This nifty weave, known as Captive Inverted Round (CIR), looks almost like a double helix. At first glance, it seems like the colors are beads, but they are in fact colored rings suspended in place by the surrounding layer of rings. This weave requires a steady hand!

Example shown uses aluminum rings with red and black anodized aluminum colors.
