This week the Diva's challenge involved two tangles...Cirquital and Munchin.
Here are the instructions for Cirquital from Maria and Rick's website. They are the original "creator's" of Zentangle/ZIAs. And below are the instructions for Munchin.
If you go to the Zentangle website, you can archive any of their patterns to see how to make them. Another wonderful website to show how to make hundreds of zentangles is from Linda Farmer. I use her website all the time when I want a new look to any ZIA.
