I saw some of these images online, and thought I would try one. They look so cool. These things are supposed to be relaxing. I was frustrated and stressed by the end of it. If I had made it coaster sized and not 9 x 12-ish or if I had worked on over several days, maybe then it would have been relaxing. But this caused me tension. It just seemed to go on and on. Now I love the look. And next time, I will break the process down into pieces. You can find some cool pieces doing a Zentangle search on Google images. Here is a Zentangle web site.
