From the Zentangle Primer: Lesson 2, page 45, Exercise 4.
For this exercise, we were to use all the same tangles: Shattuck, Jetties and Bales, but use different shading.
I think Amanda (above) did a fantastic job with this tile! I love that she used several tanglations: Bales, Hollibaugh, Florz, and Jetties! My favorite is her version of Bales. It has so much depth to it now!
