I am very disorganized too but I like them all at one place though they never seem to fit!
Mine are organized (at least according to my system of organization, LOL!) but I'm also running out of room on my single 3-shelf unit. The problem is mainly having to stack books behind others as the shelves are deep. Thanks for sharing the photo!
I would love to hear from you! (I always try to visit your blog back) I love links, so feel free to link to your blog or a post you like. Sorry, but I am award and tag free zone, I do not have the time to return. Comments are reward enough :)
