Lining Eyes : Dust a sheer, loose powder on the upper and lower lids so the eyeliner sticks better. If you are going to curl your lashes, do it now. (Otherwise you could smudge the line.). Choose the right formula. For a cleanstraight line, use a liquid version (try one with felt tip, like those from Lancome or L'Oreal). To create a softer, more subtle line, pencils are best.
