The challenge from the Diva this week is to just use the pattern "B'tweed." Immediately I figured it would be a zendala on a bar coaster. I'm itching to drop random acts of bar coasters, but only have a few so far. I'm fairly certain that bar coasters and Zen don't really mix, philosophically speaking, but I like working in the round.
The examples of official Zentangles for b'tweed all show the pebbly 'tipple' pattern, so even though this is supposed to be a monotangle, I've included some orbs. Actually, a lot of little bubbles.
The mandala is to be for focus and the object of the designs is to return focus to the center; I think this succeeds in that manner. I look forward to dropping this one into the environment and to see where it goes!
