Holding the iron vertically will create a looser curl pattern, while holding the iron horizontally will create tighter, bouncier curls. If you hold the iron diagonally, your curls will fall somewhere in-between.

If you curl in just one direction, then your hair will blend together. Jennings recommends alternating the direction of each curl to make your hair look tousled. For example, if you curl your hair away from you in one section, try switching it up by going the opposite direction for the next.
