Are you talking about a rag quilt where you sew 1 inch away from seams and then cut and the flannel ravells ?I made rag quilts and used two layers of flannel with cotton batting in middle and I also had alot of lint but that is because youcut the fibes and you want it to be soft and the more you wash it
the softer it will become I did Dinosaur rag quilts and the boys and they love them .
