Challenge #72 Crescent Moon

This week, The Diva, has us doing a monotangle (using only one tangle) with the tangle, Crescent Moon.  Crescent Moon is still one of my favorite tangles.  I still teach it as the first tangle in my Basic Zentangle class, and it continues to pop up in a lot of my ZIA's. 

For my 1st tile, I used a monostring (LOL-is there such a thing?), just a circle that I tangled inside with different color pens.  When I was done, it looked so plain that I decided to add a colored pencil wash to the outside.  I am not quite sure if I like this one or not.  For the 2nd tile, I used a more traditional string and added Crescent Moon in a couple of different ways.  One of the things I really liked, was just adding the Crescent Moon to the string, every other way, on each side.....very fun tangleation!
