I have used batting in my denim rag quilts a few times, the best one I made though had a layer of muslin & a layer of flannel inside and corduroy on the back. It is anall time favorite raggy quilt my youngest son requested. The two layers inside really added to the ( chinelle) edges. Yes it is a heavy quilt but that goes with the territory of a denim quilt. Since we live in a cold climate heavy/ warm is good. The denim quilts I’ve made go everywhere- camping trips, overnights, road trips. They are used and loved
