This is the easy peasiest of them all because you don't actually make anything.
I know, this is cheating a little, but I love book ends.
I think they add a lot of whimsy to an otherwise cluttered space.
For a while, my little girl was really afraid of going to bed at night. Reading (lots and lots of books) helped her calm down, and soon there were books scattered willy nilly all over her room.
I have always had a want for book ends, but have never had a space or need for them.
The top of her bare dresser was the perfect place. I went searching through ebay and second hand stores for the perfect set. I wanted something unique and a little bit mystical.
And I found them!
