To answer these questions, first let us dive into the history of Zentangle.
History
Zentangle was founded in 2004, by Rick Roberts and Maria Thomas. Roberts, a meditator, and Thomas a calligrapher bounded their forces and discovered the meditative effects of creating repetitive patterns. They wanted to establish an art method that was accessible for anyone to create. This is because they often heard that people did not have the time, ability, space or patience to do art. In their opinion, all these reasons can be swiped off the table due to the simplicity of Zentangle.
