The Iowa City Public Library had the idea of using their used book to make a playhouse for the childrens section.  The ideas you can find on pinterest are never ending.

I usually just seem to use pinterest for ideas for book displays, kid program ideas & projects, and book lists.  So many of the ideas are unique and I would have never thought of them.
