Armed with new bedding, I had my mom come over to help me rearrange my bedroom - along with the addition of another bookcase given to me by a friend. All it took was an afternoon and I now feel like I have a brand new space. And I think the final cost was under $100 total. Awesome!
Photos of my old bedroom for reference. These pictures actually look nice, I think. But believe me when I say that the whole room had become dingy and completely overwhelmed with books. Now, I love my books and will never throw or give them away - so I was stuck with about 5 three foot stacks of them behind my bedroom door. The new room fits them so well now!
