The shape, width and quality of the brush are to a great extent qualifying the effect you can achieve with it. You draw straight lines preferably with a flat brush, keeping the handle of the brush pointed in the direction of the line. To draw a thin line, you do not necessarily need to use a narrow brush. You can also use the edge of a flat brush for that. This brush is also very convenient for making a thick line merge into a thin one, turning the brush on its side in one fluid action as you go automatically changes the line from thick to thinner. When you come to the end of a line, lift the brush from the skin in a single smooth movement.
Hint: to make beautiful, thin lines, you mix the Water Make-up with Cleansing Lotion instead of water.
LIGHTENING
When you want to age a fair skin, you first shadow and than lighten. With a dark skin you start right away with lightening. On the dark skin lightening is done with yellow because white gets gray. Work subtly and use little water, to make the effect more natural. Apply the yellow make-up on the higher situated parts of the face.
If children have skin irritation or small cuts on their faces, you can also do the painting on the hand.
