Rustic: Style Secret: Rough-Hewn Beams
For many of us, this element is the first thing that comes to mind when we think "rustic." Not only do rough-hewn beams help to define a space architecturally, they can instantly anchor it in rustic territory, especially if they're left rough and unpolished. Use beams to frame ceilings and delineate doorways, to surround fireplaces and windows, or even to line walls. You can also incorporate rounded logs if you choose, which lends cabin charm.
Inspired addition: Honed beams against smooth, glossy white walls create an arresting contrast. Or juxtapose them with a surface that's still textural but not so rugged, such as beadboard.
