I've always doodled. Especially when on the phone. But now I've taken it to a new level after discovering Zentangles. I've never really focused on the overall design of my doodles like this!
Zentangles is a form of doodling. Rick and Maria of Zentangles.com started Zentangle and have made it popular. Check out their website to see alot of Zentangles and info.
Here's a couple of the first Zentangles I did.
And here's an owl I Zentangled. I got the idea from an owl drawing I saw in the Entertainment section of the newspaper.
