Here's my issue, I have windows and door casing that appears to be 1x6 that was custom routed, my down stairs is almost identical but has a backband. My current baseboard trim I've come to find has been screwed in by the previous owner and I can't remove it easily to cut it to accommodate backband.
Since the trim is cut nearly identically, this below picture is the style I'm going for
Ideally I don't want to add anymore width, so I was thinking of adding some shoetrim or stop trim around the outside edge to get the same look. I feel like it's wrong to do this, so before i start nailing away with some shoe trim i want to hear some ideas. The only concern i can think of would be the look of the trim from a side profile. Who knows, maybe I'm being a little OCD.
