With your stencil stable and your supplies gathered, it’s finally time to paint! Painting with stencils requires very little paint on the brush. The depth of a color is built up by applying the paint in thin layers until the desired shade is achieved. This method requires a little more patience, but results in a crisp stenciled image. If you want a more weathered look, you can apply a single layer. For a bold, sharp portrait, the paint will need to be applied in several layers.
While holding the brush perpendicular to the plate, dip the end of the brush in your paint. Work the paint into only the lower part of the bristles. Be careful not over saturate your brush. If you do, paint away the excess on a piece of scrap paper. Too much paint will leak under your stencil, and will change the accuracy of your portrait.
To apply the paint, always hold the brush perpendicular to the paper. Tap the bristles into the holes left by your stencil. Light, up and down movements are best. Do not brush side to side or press too firmly. Do this carefully, being sure not to disrupt the stencil.
Don’t be afraid to get a little paint on your stencil to ensure that you are bringing the color all the way to the edge of your image. It is recommended to use a long, thin stick or skewer to hold down the edges of your stencil as you paint around them. Your paint brush can lift the stencil slightly if it is not completely stabilized. The stick will help hold any small stencil edges in place as you tap in the paint. Again, apply the paint in several layers to build up the color if a darker shade is desired. Your paper should not wrinkle from too much paint.
