Question: How to patch up a hole in drywall.

  Options: 
 A. Cut around the area of the hole into a square, then measure the square and cut another piece of drywall to size. Hold the new piece in place and drill to the studs. Place joint tape around the edges, then use a joint knife to apply putty. Sand it down when it's dry and wipe clean with a wet washcloth.
