My chair railing, in various places around the room, is going to be butting against the casing around my doorway, around my closet, and also around my windows. The chair railing is a little more 'raised' at its highest point than the casing is, so when it's flush against the casing, you can see the end grain.
What is the most typical method for installing the railing at these junctures? I'd imagine you don't just butt it flat against the casing and allow the end grain to show...
Do I just miter a 'return' at all of these locations? If yes, should the return basically be right up against the casing so that, in effect, the outermost edge of the return/chair railing is touching the casing, and then goes 45 degrees back from there (if you can picture it...)?
