We love to organize children& books using front-facing shelves. It makes for easy recognition for kids, plus the book covers become a design element themselves. But there is one drawback to this method.
closet-turned-nook love it! we do this to every closet Bear has ever had =) he loves his very own special place. Its never this awesome or large, but it is his space he gets to decorate himself. Closets as kids spaces is so great.
