First, I cleaned the mailbox with a vinegar solution so the paint would adhere well. Then I spray painted green at the bottom for grass, blue for the sky and then I blended in some white for clouds. Let that dry. Then I decoupaged wallpaper horses onto both sides of the mailbox. (I used a decoupage especially for outdoor use.) After applying several layers, I then coated the whole box with a clear coat of polyurethane spray. The numbers were created by my DD with horseshoes that he welded together. (how cool is that?) and then I painted them a rustic brown. He then attached them to the pole. Ta-da!
