How to Find a Stud in a Wall

Optional
If you're still having trouble finding the stud, drive a finish nail into the wall in the general location where you expect to find a stud. You may have to punch several holes before you hit solid wood. The value of using a finish nail (which is very narrow) is that it's easy to spackle over and hide again. Or, if you're hanging a cabinet, there's really no need to cover up the holes.
