Felt makes great batting for things that need something but nothing too heavy or stiff.. Be very careful using felt in pot holders though.. Most felt available today is polyester..(which means it won't shrink). I have never heard of Wal-Mart or JoAnn's or any of those "everyone has one" stores carrying Cotton Felt. In fact I've been around sewing and fabric all my life and have not ran into cotton felt. I'm wondering if the bolt could have been mismarked?? I'd bet it isn't really cotton.
