Gently stroke the brush through the eyeshadow color, being sure to keep the bristles together. Move the brush across the eyeshadow in the direction of the bristles. Knock any excess color from the brush, then carefully apply the color from inner to outer corner of the upper lash line. Repeat this step for the lower lashline, but do not line all the way across the eye; Rather, stop just before reaching the inner third of the lower lashline, and make sure your line fades gradually for the most attractive effect.
