The challenge this week really was a challenge for me. There were two new tangles to try of which I had never heard of before. One was Cirquital and the other was Opus. Since I had never done either of these tangles before I followed the link and then sketched them so I would have some idea of what they were.
Then I sat down and sketched my version on the challenge.
I used the end of a frozen orange juice can for the large circle. The rest were made with a ruler that had different sizes of circles. I shaded with a Zentangle pencil I got in a kit and used a paper nub to smooth out the pencil marks. I am not sure how I like this one but I have learned two new tangles in the process of the challenge.
