I'm asuming you've got pefectly shaped and set eyes: Using kohl, line the top lid and the inner lower lid. If you soften the top line with a soft brush (particularly if you're going for the 'smokey' look), then place dots of kohl between your lower lashes as close to the eye as possible, and blend and merge them with a brush. The liner should meet at the outer eye corner. The secret is to apply sparingly; you'll still get the 'full' look, and shouldn't look like a panda unless you've got very round eyes ... I've written a Hub about it. Oh, if you don't want the blended look, then just draw a thin line on the lower lid close to the lashes that meets the upper liner at the outer corner.
But there are so many techniques depending on your eye shape etc. I'd have to see you to know exactly what's best for you.
