Q We have several antique wood frames with various amounts of warp. Can they be straightened?
A Once wood is warped it may be very difficult to get it back in shape, said Dan Gelfand of New Look Refinishing Inc. in Minneapolis. But you can try.
Remove the picture and glass, leaving the frame empty.
Lay the frame on its face on a sturdy flat surface.
Place long and narrow strips of damp (not wet) rags along the back of the frame.
Put six to eight clamps around the perimeter of the frame, clamping the frame to the flat surface.
Tighten the clamps once a day, but only a small amount or the frame might break.
Keep the rags moist.
