At a few places in our basement, we have two immediately adjacent corners (almost like a "Z"), of an inside then then outside corner, with only a couple inches along a short wall. Or around the edges of our closets (sliding doors) where it would be two outer corners right next to each other.

What would be the best way to manage this? Buying all the appropriately HORI-CORs, and cutting them short to fit? Other ideas? Many thanks!
