One of the things I enjoy most about Zentangle is that sometimes a drawing session results in something that looks like this. :) I started by reviewing tangles we've worked on so far. Next, I drew a borderless string and invited participants to do the same. Finally, I used a few familiar tangles and a couple of new but easy ones (Knightsbridge and Mist).
I also showed everyone how to draw the basic version of Huggins and demonstrated how this tangle can be modified to fit any kind of space.
