Using your nondominant hand, sweep your hair off to that side, just slightly off center. With your other hand, slip in a bobby pin vertically, up from the bottom.
Working from the bottom up, insert a row of bobby pins vertically, crisscrossing them to secure the hair. Finish by pushing in the last one downward.
Gather hair in one hand and twist tightly, pulling up.
Insert bobby pins horizontally into the base of the twist, intersecting with the vertical pins to hold the style.
Arrange the ends, letting them fall freely. Spray hair lightly to hold the style.
