I'm just about done with my mudroom built in project, but have a few small gaps where the wall/drywall is out of square/plumb/flat. Gaps are no more than 1/4".
I scribed a filler strip on the sides but didn't make one for the back for a few reasons. Now that I am where I am, what would you do? Quarter round? Flat stock scribed? Carefully applied caulk?
