Erin, the Bright Owl, posts a zentangle-inspired mandala dare every Friday here. She provides the options of doing the dare on a standard tile, a zendala tile, or full page. This one was supposed to have a 'Mexico' feel to it, but I didn't get there (phooey).
Here it is on a standard 3.5" tile. I felt compelled to make it more circular. I wanted to try it on a zendala tile too, but I can see that I'm not going to have the time.
Tangles: O-bob, Prestwood, Stoic, Tripoli and more
