Once you've finished the first section, drape it over your part, so you can create the waves for the next section underneath.
Note: Try to follow the shape of the waves as you move through the sections (so the bottom layers match the top ones). You want all of the hair to blend seamlessly together for the final look.
Once you've finished waving the side of your head, gently comb out your hair, and blend the sections together.
