There are different qualities of flannel, as folks have already said. I didn't see this idea on any other post, but you might try putting the flannel into the dryer again with an old towel that you have wet down. the wet towel may help pull the lint off the flannel...but make sure it's an OLD towel that has been washed many times, otherwise the towel lint will spread to the flannel. Also, at the end of the cycle, pull the flannel out right away and see if it is less wrinkly than before.
