If you have kids, you’ll quickly realize how hard it is to keep your books organized especially if you have a deep bookcase. Books look best when they are closer to the edge of the shelf, but kids often push them back as deep as the shelf goes. To make deep bookcases function better for your family, consider adding in 2 layers of books.
I placed my books behind my children’s books. This no only maximizes the use of the space, but it also keeps the kids books from being pushed back into the shelf.
Hope this tip helps you make the most use of your space!
