Make a boring steel front door spectacular using a wood-graining technique. Use a wood-graining rocker and several layers of brown paint mixed with glazing liquid. If you are very adventurous, this technique can support fantasy faux finishing, that is, preparing a finish that has a realistic look but not in realistic colors, for example, a bright blue wood. This finish is versatile, fitting into many decor styles, from modern to rustic.
Marbling should be used sparingly in any situation to maintain its illusion of reality. Archways and pillars look magnificent with a properly executed marbling technique. Reserve this finish for the exterior of stately, formal homes, as it would look out of place in a rural or suburban setting.
A country home or cottage is the perfect place to distress the exterior. While it is not advisable to distress an entire house, a front door, garage door, banisters of a porch, or a mailbox look charming as an antiqued accent. This technique is easy for a beginner. It only requires layers of plain paint and sanding to expose small amounts of the colors underneath to give it a worn appearance.
Faux stone looks beautiful on an archway or in an enclosed porch. You could even do it on a porch floor, but only if it is covered; the effects of traffic combined with direct weather would be disastrous and not worth the work. Faux stone is easy with a stenciling kit, or it can be done free hand by a more experienced painter. Faux granite, slate or limestone are good choices for faux finishes, as they can look very realistic when done properly.
