I do exactly the same thing as Peckish's friend - I load backings several hours prior to start quilting. However- I spritz it with a dilute solution of fabric softener in distilled water. Works like a champ. I have not ironed a backing in years- even the stubborn middle fold fades away. I can only assume the same can be done if you have a way to hang it. Perhaps over a shower rod? May have to refold after the first hanging. Best of luck with it.
