Moving in to a loft with no closets and very few walls (in lieu of the benefit of 25 windows!) has been a fun challenge. I've haunted thrift stores, eBay, Craigslist, and the MIT Furniture Exchange for decent or repairable storage furniture.
When I first moved in, the only piece of art I hung was my vintage Farrah Fawcett poster—perfect for hiding the fuse box. Of course, the fuse box can't be blocked by a large piece of furniture or art...as it must be easily accessible. So, Farrah serves a practical purpose.
But the set up left an awkward little space, and in need of evening light. Enter my sister's $5 find at the Goodwill. Took me a while to figure out what this was: someone had installed a horizontal shelf...but the base of the piece was riddled with holes. Then it hit me: the holes likely had vertical dividers, as the cabinet is exactly perfectly sized for holding 33 RPM LPs.
I painted over the cheap and ugly veneer with the same color as my radiators, so it works really nicely in my space. I covered the doors with blue burlap for some texture and color. On top is the blue and white glass shade lamp I've had forever, which ties the blue in and casts a fun pattern on the wall—but not so high as to hit Farrah with the pattern.
Lastly, I replaced the awful plastic door pulls with some really fun vintage mid-century pulls I had kicking around.
