Patching a hole in drywall

Tools you'll need: pencil, 12-inch straight edge, 4-inch putty knife, utility knife, sandpaper, small bucket of drywall mud, piece of drywall (at least six inches larger than the hole), paint.First - measure the diameter of your hole to be repaired. From your extra piece of drywall, cut a square, four inches larger than the hole. Place the square face down on a table and draw a line two inches from the edge on all four sides. Score the drawn lines with your razor blade and break-off the excess drywall, leaving the front paper in tact. Place the drywall patch over the hole in the wall and use your pencil to outline the square on the wall. Cut the traced square from the wall. Apply a light coat of drywall mud around the edges of the newly cut square hole and place the patch into the wall. Squeeze out excess drywall mud with your putty knife and let dry overnight. Re-putty the patched area, again allowing the mud to dry overnight. Sand away excess mud and smooth out the wall. Paint the area and you're done.
