Creative hobbies fulfill several needs, some within ourselves: the need to create, to work with our hands, to do something for someone else, to express love, or friendship, or that you care even if you don't know the recipient, the need to spend our free time doing something worthwhile, productive, useful, and beautiful. The upside to spending time creatively is there is a tangible item as a result. We use our words to tell someone we love them, or we care about them; but we use our hands, our time, our creativity to show them. Win, win!
