How can I repair screws in furniture with stripped holes?
Although similar to the tooth pick trick, a real good and solid fix it to drill out the stripped hole to a size 1/32 inch smaller than a piece of hardwood dowel. Apply a good wood glue to the dowel and tap it into the clean drilled out hole.  After the glue has dried, flush cut and sand the dowel smooth to the wood surface. Now drill a small pilot hole and re-install your screws. This should give you a strong permanent fix.
