Great in the library, wood paneling, built in bookcases and embrasured shutters. Raised panel shutters that fold into pockets built into the window jamb. This is a clever architectural detail used in the 18th and 19th Centuries when brick homes required a wall of exceptional thickness, often exceeded 12 to 14 inches.
