Having trouble making your winged eyeliner look perfect and even on both sides? Here's a trick that might help you!
Get some scotch tape and place one end of the tape on the outer corner of your eye. Place the other end on the end of your eyebrow or a bit below. Smooth it out so its all pressed against your skin then apply your liquid liner. This is good for beginners because you can be as messy as you want as long as the messiness is on the tape. Eye liner, especially liquid liner, takes a lot of practice to get perfect so keep practicing!!

Do you have oily skin?
