Have you ever heard of tightlining? Me either but I have heard of lining your upper and lower lash line, however this is a bit more complicated. Basically, you put eye liner whether gel or pencil in between each lash in your lash line. It's a fabulous way to add great definition to your lashes without looking like you're actually wearing a thick layer of liner. It's easy to become a huge fan of this look.
