I use flannel for batting for what I call "wash quilts." I make a quilt sandwich with top, one or two layers of flannel and backing.. (Flannel and backing should be about 4 -5 inches larger than the top. I then stitch lines one inch apart either a straight stitch or a small fancy stitch. After the layers are sewn together, I wash it in hot water with retayne ( to preserve the color fastness) and then dry on low. I wash and dry it about four times. The flannel shrinks about 5 - 10%, causing lots of nice little puckers. Using the retayne keeps the colors bright. These quilts are great because you can wash them whenever you wash your sheets, if you want.
