A timely Crate & Barrel catalog and a fortuitous trip to the C&B store netted me my shelving solution:

I like them! I think they personalize the space by having more of my “stuff” around. And they really weren’t that expensive.
Oh, and the best part? I was able to unpack two more moving boxes. Leaving me with just one box if miscellaneous crap left.
