I got the first mat successfully cut. I went to the art supply store looking for Pam corners, but they had nothing like that. And the deadline is imminent, so I just spread rubber cement and am waiting for it to dry a little for secure bond. The corners will have to wait for a future show. Meanwhile, it is heating up and I'm starting to sweat, which makes photowork difficult. When I finish this one, I have to go to AC Moore for another mat, but I'll have to shower and dress first.
