I made this ring last night, following the instructions I found here:

Which I found as a link from this page:

It was under "Anillos/Rings-2". There are quite a few interesting collections here for jewelry, kumihimo, sewing, etc.
It was surprisingly easy, just required some seed beads and a few small lucite beads. Took a couple of hours, I think. I had never done peyote stitch before, as far as I can recall, but I figured it out from the pictures (the steps in the instructions aren't entirely helpful on that). Once the band itself was made, joining it up into a ring and adding the decorations is very clearly explained in the instructions.
Today I discovered that the peyote stitch was better explained in her other free tutorials here:

From there you can get to her tutorial shop, where she sells tutorials for other lovely things.
