I have been "zentangling " lately. Zentangle is considered a meditative art form. In the days when a person's phone was connected to the wall, you would "doodle" on a piece of paper while you were talking to the other person. Well this "doodling" is similar to "zentangling." In fact, you start with a pencil doodle and fill-in the doodle with small repetitive strokes in ink. These patterns you create are called "tangles."
Drawing the repetitive lines have a way of creating calm along with your own small piece of abstract art.
I thoroughly enjoyed creating my first Zentangle rug "My Zen 1"
