I was watching a quilting show the other day and they were mentioning using your applique pressing sheet to iron you fusible webbing, (or so I thought). Point is I did that but I ironed the glue side to my pressing sheet and it has stuck and made a terrible mess. Anybody have any suggestions on how I can restore my pressing sheet? I have tried soaking it in hot soapy water but it's still a mess. Have I ruined it?
