Here's what I've done. I cut out a 7"x25" hole. It extends beam to beam horiz and enough to cover the hole vert. I cut out a piece of 5/8" drywall and nailed in. The problem is that it doesn't look very good, even after painting. The paint color is right, but it's still pretty evident that the piece was put in. Any tips? If not, where would I go to look for some? Thanks in advance.
