Pro-tip from gunsmithing school regarding all the toothpick and golf tee suggestions: The nice looking way to do it is to drill out the old mangy hole in the wood, and then fill it using dowel rod of the appropriate diameter. Determine depth of drilled hole, cut off length of dowel slightly longer, sparingly apply wood glue, press into hole and then lightly tap into place with a mallet. Wait for glue to dry, and sand (using a sanding block) to an even finish. Drill new pilot hole for screw.
