I'm finally starting to complete the repairs around our 95 year old house that I know how to do, and need to start some of the ones that I'm in the dark about. Here's a weird one. When we took the carpet out, we discovered this hole that is in the flooring, baseboard and door jamb. It is about 1/2" out from the wall at its widest, and 1 3/4" up from the floor at its tallest. I'd just put quarter round down and call it done, but I don't want to put quarter round on the door jamb, I think it would look weird. How would you approach this?
