joannes has lots of different fleece fabrics to choose from; different weights, some are wind proof, some are thin, some are thick, some are solid, some are prints...since you have a coupon to use just go through and see what catches your eye then start narrowing your search by feel and reading the end of the bolt...you want fleece you can wash the same way you will wash the quilt. and when you are backing the quilt remember fleece has stretch. you want to lay it out smooth without stretching it or your quilt will be odd shaped. lots of pins or basting to hold it smooth while you tie it.
