Book Covers

 I was just thinking about what I do to save my book covers at the start of summer. Basically, I put one into another's little pouch, then roll it up to make a ball using the opposite end. Then I stuff the ball in another book cover and so on. The end is a ball of book covers, and I can just peel off a book cover when I need one! It is really squishy, actually. 
 Do you guys do anything to your school supplies to store them easily for the school year? I know it is early to be asking by the way, but post in the comments anyways!
