Sometimes the screw securing a hinge to a cabinet door becomes dislodged and stops gripping the wood. Over time, the screw begins to gouge the cabinet interior, and the door becomes crooked and difficult to close. Set things straight by removing the door and hinge, and then fitting a cut chopstick into each stripped hole. Fit the chopstick in tightly, and tap it in with a screwdriver until it's flush with the inside of the cabinet. Now that you have some wood for the screw to grip, drill a new hole at the center of each chopstick. Finally, reinstall the hinge and door, and close the door on this cabinet conundrum for good.
