Hi,

I'm recessing these shelves inside a wall in the attic (there's space
under the roof):

I'm not sure how to finish them on the outside. Should I have matching
trim that will cover about 1/2" of the side walls of the shelves? Or
should I finish the corner in drywall and have a niche look? Not sure if
I'm asking clear questions, happy to clarify.

Many thanks in advance,

Aaron
