A mermaid's braid

The other day Gwen Fisher from beAd Infinitum posted this on her page. Usually when I see the word "math", I run in the opposite direction. This time I watched the video and of course I had to try this.

First I loomed three strips in white lined AB beads, emerald green, teal and capri blue for an ocean look.

After reweaving the warp threads into the strips, I started braiding using the instructions from the video (thank you, James Tanton).

Ocean colors - I'm even reminded of waves here - request pearls. So I added one white button freshwater pearl on each of the crossings. That way they also keep the braid from slipping.
I'm really happy with the outcome, what do you think?
