A favorite method for a lot of quilters, me included, is to fold our fabric so everything is one size, making it easier to store it. Here's a link someone posted a while back:

I don't do the last "fold in half" because I have a deep bookcase. Ir you use the search feature at the top of this page, you can hunt for "fabric folding" or "organization." There's been a lot of buzz about those lately. Welcome to the Quilting club!!!
