Then, she can use it as a template for her cat eye. Trust us, this is simple to DIY! Ensuring that the patches are aligned closely with your bottom lashline and the corner of your eye, trace your upper lashline from the center of your lid out to halfway towards your brow with your favorite liner.

Pro tip: do this first with a pencil, then layer a liquid liner on top for a more dimensional and durable wing. (Plus, you'll get a practice run with the pencil.) We like Urban Decay 24/7 Glide-On Eye Pencil in Zero ($24) topped with Stila Stay All Day Waterproof Liquid Eye Liner in Black ($22). Both formulas are waterproof, so you don't have to worry about smudging or smearing.
