Books are not made to be hidden away in cupboards. I know a lot of people don't like their books to be showing, but if you haven't already then now is the time to take them out for display.
Books are really decorative, adds personality to a space and just take a look on the covers of a lot of books - they are often really beautiful and a work of art, so why not display them as art showing the frontside of them on shelves.
You can choose to show the front of your favorite books or ones that are really beautiful and have others only showing the title like you normally would - just like you see in the library.
This way it's easy to change up the decor of your room just by changing the book-covers that you are displaying - you can even open up a book or two and display a favorite picture in the book - just like changing a normal picture you would display on the wall or a shelf.
I totally love this idea and will do this in my livingroom or office, when I hang some shelves or get a new bookcase - books are cool - don't stow them away.
