Closed corner frames are the ultimate in fine custom framing and can come in styles from modern to elaborately carved classic. The traditional technique, used for many centuries, will involve building a frame first and then applying the finish, which means that the joints are much stronger and more durable than mass-produced open-corner frames.
Since these frames are hand-made, there is often a carved ornamentation in the corners of a frame, which distinguishes it from regular frames and gives it an exquisite, finished look. The main feature is an invisible corner joint which provides seamless flowing frame design.
