Pat one half of your sponge into the white makeup. You may need to pat the sponge first in a bit of water, then the makeup to get the right consistency. Always pat the back of your hand with the sponge first, to test how it will look.
Apply to the face, using a soft patting motion. It is important not to wipe the makeup on, or you'll have some obvious streaks. If the white isn't heavy enough, don't add any more. You'll be touching up the white with a brush later.
Now, let's add some black.
