Do you do Zentangles?
Our friend Jo has just directed us to www.zentangle.com
A website in America, where they give a doodle a better name, and you can 'study' it with a lesson plan and a 'kit' and everything! Patterns like verdigogh, opus, paradox, jonqal, and cadent,  you probably drew when you were young, but never knew it had a name clever name!
It's repetitive and beautiful and satisfying and a healthy way to leave the world behind, which makes it important.
