Dip the angled side of the brush into the shadow and tap off excess. For crease contouring: Press the angled side horizontally into the crease with the longer end toward the outside of the eye. For a bolder effect: press vertically into the crease with the longer end downward. For corner contouring: Sweep the angled side downward from the outermost area of the crease, toward the lashes, finishing above the iris.
