The fabric companies use this warning to cover themselves because the fabric has not been treated to be flame retardant like children's sleepers and pjs. This does not mean you can't use it for a quilt or clothing for a child. The warning is for "close fitting" garments like sleepwear. Of course, they don't tell you that the stuff they use to make children's sleepwear flame retardant is nasty and has carcinogens in it actually washes out after a few washes. I never bought my kids jammies because they hated the feel of them and I always used flannel from the fabric store that said not to use it. The companies put the warning so that if in the event that you did use it and your child got burned, they would not be responsible and you could not sue them. My husband always says, "They don't smoke so I wouldn't worry about it."
