Creating the perfect cat-eye look with eyeliner can be tricky. Not only is it hard to get the ideal flick and shape, but you also need each side to match. For an easy way to nail the perfect feline flick, try using a spoon or some tape. Start by creating a straight line from the outer corner of your eye following the edge of the spoon. Then, trace around the curved edge from the end of your flick back down to your lashes and fill in the wing.
