Another variation, is instead of using eye liner, you need a 1/4 angle brush (a flat slanted brush) and use your eye shadow in the lower lashline using soft strokes. What this does, is create a soft smokey look, linking the upper lash line to lower lashline and it looks softer than pencil eye liner.
I think I do something similar I have a nars eyeliner push brush, its great!
