@parus Indeed the doodling is very rhythmic and soothing. I find Zentangle and the repetition of lines and the swirl of pen to paper to be hypnotic and very calming. In my crochet work, the rhythm of the hook and the yarn together will almost invariably put me to sleep after about 45 minutes! As a passenger in the car, with my crochet, I'm a happy camper and asleep after a short amount of time. My husband says I never drop the hook or the yarn I just fall asleep very quietly. He knows I'm rarely so relaxed.
