One of them is how to contor corectly. When you contor on your cheeks your make downword motions, and when you contor on your brow you make upward motions.
Another tip is your eye shadow aplicater. Get the right one! The cheep $0.99 store ones don't work and sumge your eye shadow. Now who wants that. It ok to spend a little more mony and get the $5 pack. Those work and don't smuge.
