If you are cutting your own hair and want to get "interest" around the edges, just twirl the side strands together, then cut diagonally along the bottom. (Start long. The trick with cutting your own hair is to start "long" then cut gradually so you can cover any mistakes.) First cut dry, then even out when wet and correct cut when dry again. Follow the design of any old haircut you may have to keep its shape. You just want to make it shorter to deal with the length it has grown in.
