To achieve a Victorian look on an interior wall, try a beadboard wainscot. You can buy beadboard at your local lumber yard. Here are some things to keep in mind when installing it yourself. Run your baseboard first to avoid creating a dust collector. Use a drill and a jigsaw to cut holes for outlets. Fit each board together snugly, then nail with 2-1/2-inch finish nails. Angle the bottom nail into the tongue of each board. Base nail the top and cap it with the molding.
