You can pencil your brows lightly or use a small stiff brush and brown powder to get a soft brow. If you use a pencil, it helps to brush the eyebrow with a tooth brush to blur and soften the pencil. You don't want your eyebrow to look as if it was drawn on with a marking crayon, so be gentle. To determine the length of your eyebrow, draw an imaginary line from the tip of your nose up to the outer corner of your eye and up to the brow. That's where your brow should end.
Eyebrows begin above the inner corner of the eye, and taper off to nothing.
They should not be heavy at the outer end. The eyes are the most fun to paint, but also possibly the most difficult to do well. First, avoid brightly coloured and frosted eyeshadows. I know they're fun, but they can age your eye. Learn to contour your eye with neutrals like taupe, charcoal, brown and off white.
