"I always use pen eyeliners because I think of it like a marker. Start with the wing! Then, use a cotton swab to make them even. Just fill in the triangle shape after that. Also, I tend to do better when I don't put a lot of pressure on myself for it to be perfect. If you psych yourself out, you'll be too nervous to draw a straight line."—Brillian Qi-Bell, Facebook
