Take a 3'piece of string. Tie ends together. Lay the string on a flat surface. Push and bend it into small circular inward and outward twists and curves of different dimensions several times(left). Draw the best arrangement (right). Oh yes, there can be straight edges too! Why not?
With soft undulating lines or sharp edges, each in distinctive in flow and outcome. Some have openings and some not. Picture an image in movement and you have dancing lines.
The next page will complete the crazy circle constructions. What's next? Well, how about a Rat Maze? where no curves are allowed!
