I'm about to install a 24" x 60" section of 1/2" drywall, to patch an area I cut away for access to make repairs. The bottom (long) and one side (short) edges of the patch will be hidden, but the top and left joints will be made mid-wall, and I'm worried that they'll be visible as bulges.
The patch has the usual tapered edge on one of the long sides, so I could install that edge up or down. The edges of the hole cut in the existing wall are of course not tapered.
Should I try to taper the existing drywall before doing the joints? Or should I just bite the bullet and do a whole lot of feathering?
Edit: the short seam is on top of a stud, while the long seam spans several 16" stud bays.
