Tonight, I purchased this shelf. It's wider than a traditional bookshelf, so baskets and other containers will fit on it very nicely.

I also purchased 4 zig zag pots in white. They're a little over 4 inches tall, and look like empty cupcake baking cups- dreamy, gigantic cupcakes, that is. I like how they add whimsy in contrast to the square plastic boxes sitting next to them. I placed two each on the ends of two different shelves. They'll be perfect for miscellaneous junk that doesn't fit in any other category.

I love cupcakes.
