For the woodworker, "finishing" an edge of a table top, a chair seat, any larger surface, is never dismissed easily. Will it have a Beveled Edge, a Profiled Edge, a Molded Edge, an Edge-band. Will the Edge-to-Edge Joint or Edge-Joined Boards be simply glued? Have Splines? Have a "Biscuit"?

Equilibrium Moisture Content
According to its moisture content, wood will either emit or absorb moisture from the surrounding air until the moisture in the wood balances with the moisture in the air. When this point is reached, the wood is said to be at equilibrium moisture content (E.M.C.). Since wood is exposed constantly to daily and seasonal changes in the air's relative humidity, the moisture content wood itself makes changes are constant, even if only slightly, but therefore changes in its dimensions. This is the reason doors and drawers often stick during humid weather but work freely the rest of the year.
