I did see the Stencil Glue in a video from the C&C lady Mel, I think, but it is just so annoying that I did what they said and used the mat as instructed in the Quick Guide and now I've ruined it. I have seen a LOT of advice on fixing mats but I am still hopeful that I might get a replacement, because this really shouldn't happen. I have always found Graphtec to be good for customer service, going back to when I did have a Craft Robo so fingers crossed.
