MrsDrPoe: House Progress, Week 4

It's another Foto Friday on the blog!  As promised, here's our progress from the fourth week of home renovations:

Kitchen: painted the hardware black
Living and Sun Rooms: began laying flooring
Upstairs Closets: trimmed and painted white (2 coats where necessary)
Upstairs Baseboards: painted white
Spare Bedrooms: trimmed and painted 2 coats of brown


We're super close to being able to put carpet down upstairs and also to show finished pictures of the living and sun rooms!  The picture I'd like to share with you today comes from Mr. Poe's closet:

This section is about 2.5 feet deep and has a maximum width of 8 inches.  I have no idea why it exists.  So for something a little different today, I'd like to poll my readers...

what should we store in this very narrow, awkward space?
