I, of course, have never had this problem either, (ahem) but I have kept this solution in mind---just in case, you understand, that I should actually have a wonky quilt. If it is unrepentent with "spot" steaming, You might try very carefully and very tightly pinning it down to the carpet--use your big square rulers, etc to make sure it is totally as square as you can get it--then spray it generously with water in a spray bottle--just soak it pretty good--and then let it dry completely, on its own, like for 24 hours. Then pressing it, and it will be a lot better, if not perfect. This is called "blocking" and it works. (I've been told.) :lol: :lol: :lol: good luck. Let us know how you come out!
