From the Zentangle Primer: Exercise 1, page 33.
For this exercise, we were to create another Zentangle, using the same four tangles as the first tile. However, this time, we were instructed to shade each tangle differently.
In addition to changing the shading, I also changed the style of each of the tangles. I chose to wrap Florz around a bobble and give it more of a 3D, or dimensional feel.
