I designed and thought up this bookshelf for my classroom after seeing so many neat ones on Pinterest, that didn't quite fit my needs.
The one I was most impressed with, and used to create my own shelf is here:

I hope my tree inspires you to take on a new creative treasure for your own sweet children!
