I tried doing Zentangles and found it helped me learn how to do continuous motion. If you are not familiar, just Google "zentangle" and "zendoodle", then grab a pen and paper and give it a try. It's basically the same motion and you you can do it anywhere. I carry paper and pen in my purse and while I am sitting in the doctor's waiting room, I can do quite a bit of practicing.
