Whichever eye liner you choose, apply color as close to the lashes as possible - between lashes, if you can. The line on the top lid should go from the beginning to end of the lashes. You may make the line thicker in the middle of the lid if you are trying to minimize the lid. Be careful about lining under the eyes. It can have the effect of closing the eye up. Some eyes need a lower-lash liner to help define them. If so, get it as close to the lashes as possible. Aim your brush on top of the lashes. Sometimes, lining the outside corner is all that's necessary, but if you do that, be sure that you blend the line so you don’t see where it begins and ends. A lash line that ends abruptly does nothing for the eye; it just calls attention to itself.
