I don’t know exactly what wheel I was using, but the techniques can be used for any combination of wheels. The outside pattern is an example of a pattern with many points – one for each tooth, in fact. Rather than make the result boring, I cycled through the colors of the rainbow, red-orange-yellow-green-blue-indigo-violet-pink, changing pens before the pattern came close to itself. The inside pattern had fewer points. I used holes 1-3-5-7-9-11-13-15, lining the hole up with the same spot on the ring and changing pens for each hole, with the same series of colors. Hmmm… I think I should make a video about this.
