Observe whether the rabbet needs to be enlarged in width or in depth to accommodate the painting (Figure 1). If it appears to be a compatible fit, carefully place the painting in the frame and examine the fit. Measure the painting and compare the dimensions to the frame opening. Place the frame face down on a clean, padded surface or on padded blocks (consult CCI Note 10/2 Making Padded Blocks ). If a painting is framed and the frame does not fit or appears insecure, unframing the painting to make improvements to the frame may be required (consult CCI Note 10/12 Removing a Painting from its Frame).

The basic procedure for framing paintings on canvas attached to auxiliary supports (stretchers or strainers) is outlined below. Whether framing is undertaken by museum or gallery staff or by a commercial framer, a number of guidelines should be followed. For these reasons, the frame must be respected as an essential part of the painting’s history. Furthermore, many frames carry vital information in the form of labels, inscriptions and stamps. In some cases, the original frame was chosen or prepared by the artist and must, therefore, be considered an integral part of the work.
