Triangle or quarter circle shaped corner shelves would look very nice. You can find paint grade wood ones and paint to match the molding or walls; wood ones that match your cabinets exactly, if you're really lucky; glass, if you want an uncluttered look and it fits your kitchen; or, if you have leftover granite, made out of granite. I'm attaching a link that should give you an idea of the variety. Cute cat, abbycat! Here is a link that might be useful: Corner shelf ideas

Interesting dilemma! If this was my house, I'd leave the tv where it is, paint the back wall of recesses black (yes, black) then add shelves that fill the whole width and about 5 of them on each size. Make the shelves chunky an a medium tone wood. Replace the existing mantle with one more chunky and the same wood as the shelves. Decorate the shelves with interesting objects and collections. if you find that to be too much shelving, perhaps put built in cabinets with doors on the lower half. Good luck!

Hi, deb - Glad that helps! I like the etagere to go higher than the vanity, and it would look nice with a plant on the top shelf. A plant, by itself, looks fine too, the bigger the better IMO.
