Last night, I popped over to the Container Store and picked up the pieces for a seven foot bookshelf in ash (or some similar light wood). I put it together and it looks real snazzy. I have gray walls, so the wood makes a very nice contrast to the walls. Snazzy, really.
I underbought the shelves. I need a few more. As the weeks go buy, I'll buy more pieces to fill out the office. Over the vent, I plan on some 18"x20" shelves. I'll put boxes on the shelves, and store lots of stuff that way. Eventually, I'll get around to redoing the desk area. I will then be a storage god, and quite a bit poorer for it.
