any quilt you would use flat cottons for you can use flannel for- it is a wonderful fabric to use- makes soft-fluffy cozy quilts.
the only thing to think about is---it is good to starch before cutting for better cuts- (because it tends to be a bit more stretchy) and the thinner-lesser quality flannels may fray a bit more-so you might want to increase your seam allowance to 1/2" instead of 1/4"...other than that- it is a wonderful fabric for quilts of all kinds.
