If you haven't noticed, I wear winged liner practically everyday. I love it, it's a little classic and a little french gamine. I have gotten pretty good at it through a lot of trial and error. I have read an endless amount of "how tos" but none of them seemed to work for me. So, I thought I would share my technique in hopes that this helps you create your perfect winged eye...
What you'll need:
Liquid Eyeliner
Eyelash Curler
{I use: Cover Girl Line Exact Liquid Eyeliner, Maybelline Pulse Perfection Mascara, Shu Uemura Eyelash Curler}
1. Start out by taking the liquid liner and drawing a thin line on your top lash line, starting in the center and working your way out.
2. Next draw a diagonal line out from each corner of your eye. Follow the line of your lower eyelid and point the line toward the end of your eyebrow. Look in the mirror and make sure they are even on both sides. 
3. Draw a thin line on the bottom lash line connecting to the corners. This step can be left out if you don't line your bottom lashes. 
 4. From the middle of your eyelid, draw a line outward until you meet the corner of the diagonal line. Fill in with liner.
5. Use Q-Tip dipped in eye-makeup remover to fix any imperfections.
6. Curl lashes, add mascara starting close to the lash base working upwards, and voila' the perfect winged eye.
