Use this simple three step trick to figure out your ideal brow shape: First, take your eyebrow pencil and, using a stick, line up the inner corner of your nose with the inner corner of your eye; make a mark with your pencil there. This is where your eyebrow should start. Next, hold the stick at an angle from the outside corner of your nose through the outer corner of your pupil and make another mark this is where your arch should be. Finally, line up the outer corner of your nose with the outer corner of your eye to make the final mark your eyebrow should end there. Use a powder or pencil to fill in from mark to mark to create your best brow.
