L'villians, looking for advice and sources. We need to put a removable cap on a small hole in our livingroom ceiling. I want to find a decorative cover that looks like it could have been an original part of the house. I've considered art deco heating-duct covers, but would like to find something about half the size of a normal duct cover -- so maybe 5" x 5", potentially. Does anyone have a suggestion? Thanks!
