Nah, all the pictures of the kids and grandkids are crowded at the front of the shelves. Plus a few unicorns, three shelves in the living room hold video tapes in drawers, some extra books (yep, double stacked)... And on top of the bookcases, my Star Wars and Babylon 5 12" collectable dolls (still in their cases to protect them)! And more books...
> P.S. Sometimes you can hang things over the _front_ of bookshelves, _if_ you have a few shelves of books you don't need to access often.
