On my "to do" list is to finish our office space. It's more of an office alcove --- just a corner of a room. It's off the kitchen and generally out of eye-sight. The good news is because it's out of sight I haven't felt any rush to finish it. The bad news is because it's out of sight I haven't felt any rush to finish it. :)
Anyways, there needs to be book storage. Check out this very simple inspiration photo. I think all I'd need is some white Ikea shelves and some organization.
