The wainscoting in our dining room is a favorite of my wife. This wall paneling looks so rich on the walls and sets a tone that you can't get any other way. The wood paneling system I chose was so simple to install. The paneling layout was done by the factory and required a minimum of effort to get it from the boxes onto the walls.
Custom millwork is often not that expensive. Custom woodwork price drops dramatically as you have more made. Order 100 more linear feet than your woodworking project needs...just in case of mistakes.
Door trim and window trim installation is not as easy as they show on t.v. Use correct tools, practice trimming out closet interiors, and above all learn patience.
