wide door and wide cabinet at a home improvement store, attach them, trim them with baseboard, then prime and paint them both. The mirror and cushioned seat are an added bonus. What a marvelous hall tree for a foyer or narrow wall space.
The headboard was an old door that Jessica had. We chopped off about a foot and and added crown molding and painted it with Krylon Emerald Green. The panels inside are covered with Ikea fabric and I put nailhead trim along the insides.
