I was a snob about Zentangle at first because "that's only doodling."
But I admit that doodling, as a purposeful way to relax the mind and body, is a new and valid concept and deserves its own name.
Then I get to be a snob because I don’t want to be found doodling according to someone else's ideas, copying patterns I got from books.
My own thing isn't nearly as pretty. But here it is.
These are pages from my sketchbook that date from before Zentangle was a thing.
