This is a really simple thing to do with the students in your community. Those school books start coming home around the first week of school and one of the best ways to protect them is with a simple covering made of paper or plastic. There are a variety of items you can gather to help the kids decorate or cover their books. Large Paper bags are great and can be colored on, stickered up, or painted so that each student gets to show their individuality.
I found this great article on how to use shopping bags to make a book cover. And you can use these simple directions for making book covers out of almost any material.
