one of the best ways to get that porcelain "look" is to layer your make-up. But before you even start, shave (even if you're a girl) it's the fine hairs on your face that will throw it off and give a texture. IT also works really good to wax down your eyebrows. Any good costume shop will sell the wax sticks and they're pretty cheap. Once the wax is smoothed out, you can go right over it with make-up and it hides the hair better. Then do a light layer of your white, then "setting" powder (Ben Nye is good) then another layer of white - set again - and then add your cracks. I use all MAC and Ben Nye, the MAC color pots have great stuff for making cracks that you just paint on with a brush and blend a bit. As it gets closer to Halloween, they'll put up tutorials on their website for different looks, too. =)
