Royal Classic set of 14 Individual Wooden Wall Photo Frames

The frame along with its mounts protects and often makes the art look better. Art work framed well will stay in good condition for a long period of time. Joan Miró once did a work specifically to frame with a flea market frame. Many painters and photographers who work with canvas “gallery-wrap” their artwork, a practice wherein the image extends around the edges of the stretched canvas and therefore precludes use of a traditional picture frame, although a floater frame may be used. As picture frames can be expensive when purchased new, some people remove the pictures from a frame and use the frame for other pictures.

Picture frames have traditionally been made of wood, which is still the most common material, although other materials are used including silver, bronze, aluminum, and plastics such as polystyrene. A picture frame may be of any color or texture, but gilding is common, especially on older wooden frames. Some picture frames have elaborate molding which may relate to the subject matter. Complicated older frames are often made of moulded and gilded plaster over a plain wood base. Picture frames come in a variety of profiles, but generally the lengths of moulding feature a “lip” and rabbet, the function of which is to allow a space to hold in the materials in the frame. The lip extends usually about a quarter of an inch past the edge of the rabbet.
