Zentangles are miniature pieces of unplanned, abstract black and white art created through a very specific method from an ensemble of simple, structured patterns called "Tangles".
The creative options and pattern combinations are boundless!
The Zentangle art form and method was created by Rick Roberts and Maria Thomas.
Zentangle is a registered trademark of Zentangle Inc.

Anyone can do it,and so I am giving it a try. There is much to learn, but it is very relaxing.
I can't draw, but this works for me, as per some of my examples.
A work in progress.
