I have a single French door between my kitchen and dining room. Over the

straighten it out, or should I install a new one.


Old fashioned way to flatten a warped table top was to put a damp
cloth on the concave side, wait until it absorbs enough moisture
to flatten out and then clamp it to 2x's until it dries. Works
very quickly and easy to make it over-correct.
