Paint the frame, front and back, with purple paint. Let dry completely.
On the "Friends" stencil, cover the areas close to the word "friends" with tape so that the paint doesn't get through those areas.
Place the "Friends" stencil on top of the painted frame. I secured mine to the side with a little tape. Dip applicator in white paint and pounce off the excess paint onto a paper towel. Hold the stencil down with your fingers and pounce applicator onto the stencil. When stenciling, remember to pounce your applicator straight up and down and not at an angle. Pouncing at an angle can cause the paint to get under the stencil. When finished, lift the stencil off the frame and wait for the wait paint to dry before moving on to the next step.
To add the polka dots, place the "Dots" stencil on top of the frame. You will be able to see the word "friends" that you just added through the dot stencil, which will keep you from accidentally painting a dot over the letters. Use the pink, white and light green paint to add the polka dots using the same stencil method as above.
Allow all the paint to dry, then outline the letters and the dots with a black Sharpie. Leave for about half an hour, just to make sure the marker has dried. Spray or coat with a gloss sealer.
