So my friend sent me this picture, this is everything you DONT want to do to your eye brows. lol stay away from the sharpie.
The correct way of shaping your brow to your face is this, the start of your eye brow should be lined up with the inner corner of your eye. The ending point of your brow should be diagonal from the outter corner of your eye.
I did this eyebrow tutorial awhile back, I am going to update it but you can check it out below for now.
