My husband draped mine over my machine and tote in the back of my car. He loaded it in there in the morning so I could go to class right after work. It got so warm that day that it warped my cutting mat. I then laid it in the back of my car, a Pontiac Aztec, a flat area, and let it warm up all day. That seemed to really help. Try anything. What have you got to lose? Good luck!
