Step 3. Spray paint the mirror
Read the instructions for your spray paint before you begin spraying. It might be a good idea to practice using spray paint first, as it can take a while to master. Common problems are holding the nozzle down too long, which creates drops of excess paint and spraying too close or too far away. It is usually best to use even, horizontal strokes and work your way down. If you miss some areas, allow the paint to dry (about five minutes) and lightly spray again over the spots which need more coverage.

Step 4. Reveal the effect
Once the paint has dried, peel off your stencil and see what you have created! This is the best part :). Using different colors on mirrors is always interesting. Try clear matte varnish spray paint… this can give a very cool result - a little like an etched effect. White works well, too.
