Can someone help me with my new big shot? I tried cutting the pillow box out and it is cutting the crease lines. The long one that is the side seam of the box seems to be fine but the crease line to fold in the ends is cutting through. I first tried cutting 4 at once and it totally cut through 3 of them. So i started cutting one at a time and it is cutting through most of them. The sandwich I am using is first a cutting pad, the die with foam up, paper and then another cutting pad. Should I be replacing the top cutting pad with the crease pad? I am afraid that I will ruin my crease pad. thanks!
