I cut some L-shaped notches in the corner between my walls and ceiling in order to pull some electrical wires through. Now I'm not sure how to repair the hole... should I just cake in joint compound to fill in the hole, or cut some small pieces of drywall to fill in the hole?
One method that came to mind was to cut small wood pieces an inch or two longer than the (already small) hole, put them behind, screw them to teh existing wall/ceiling, cut small drywall pieces to fill the notch, screw those into the wood, then put on joint compound + corner tape, but that seems like a lot of work for a hole so small. I'm not sure I could even fit the wood bars through a hole that size.
I found many resources online describing the process of pulling wires through corners using the notch method, but nothing describes how exactly to repair the drywall when complete.
