Wall frames are a traditional design element commonly found in Georgian and neoclassical settings. However, they can be right at home in virtually any style—even a house that's decidedly modern. The frames are a purely decorative element that breaks up expanses of wall and add architectural interest. Popular locations include an entry, a hallway, a stairway, a living room, or a dining room.
You can give the area inside a frame a distinctive treatment by choosing a different paint color from the rest of the wall and even choosing a third shade for the frame itself. If you do this, save yourself a lot of work by painting the walls before installing the frames. Prepaint the frames, too. Wallpaper or stenciled motifs are other possible treatments for the field inside the frame.
Expect to spend about 1 hour for a single wall frame; time per frame decreases when you're making and installing a batch. Plan out the sizes of all desired frames before you begin.
