This set of six different eyeliners caught my eye right away, and I just had to have it. In this demonstration, I used Stila Stay All Day Waterproof Liquid Eye Liner in Black and Make Up Forever Aqua Eyes Eyeliner in Black. My two favorite liquid eyeliners were the Stila and Eyeko because of their great application tips that are kind of like calligraphy brushes. My two favorite solid eyeliners were the Silta Smudge Stick in Stingray and the Make Up Forever Eyeliner mentioned previously.
Cat Eye Tutorial:
Take the tip of your eyeliner and draw your first line from the outside edge of your eye until the most outside point of your cat eye.
Draw your second line from the center of your pupil to meet the line you just drew. Go over these lines a couple times from different angles to make sure they look straight.
Fill in the cat eye outline with solid eyeliner to complete the look.
