I'm going to start with the following:
What you need:
Eyeshadow base/eye primer
Jumbo eyeshadow pencil
Liquid eyeliner in black
Pencil eyeliner in black
Let's get started (please refer to my 'Map Of The Eye' on your right):
Prime your entire lid and crease for long lasting smudge-free wear and this will keep your eyeshadow from creasing.
Apply Jumbo pencil to line your lid. It depends on how thick you want it to be.
Use blending brush to smudge/soften the harsh lines.
Apply a nice brown shadow (preferably matte for monolids; AVOID shimmery shadow as it will make the eyes look swollen or puffy) to your crease area or below your brow bone. This brown color can help to enhance the monolid eye (it's like faking the crease!). In other word, to create eye contour and crease effect.
Oh ya, don't forget to apply highlighter to your brow bone. For those with monolids, DO NOT use a shimmery highlighter as it will make the eyes look swollen, instead use a non shimmery highlighter.
Lastly, you may apply your false lashes.
