So, I have done very little drywalling, maybe 15 sheets or so. I know butted joints must end on a stud. So the end of the drywall is 3/4" onto a stud for each piece. That seems sparse to me. In the past I have added a 2X3 to the existing stud to allow more area to support the dry wall and add a wider width to screw into. Is this overkill? Thoughts
