Start by shaking up the eyeliner tube so the formula is nice and smooth.
Get in the right position. Make sure your hand is steady by placing your hand on your cheek as you apply.
What works best for me is to apply a layer of mascara first, because it helps to keep a straight steady line.
Get as close to the lash line as possible and start in the middle of the lash line and work your way out in a series of short dashes, building the line as you go.
Create the wing. Draw a small triangle from the end of the line with the upper lash line and fill in the space.
Now, get as close to the inner corner of your eye as you can and VOILA. Repeat on other eye.
