I am in the same boat! I bought a cricut cake this summer and have been experimenting. Freeze your mats for 10 minutes, up to 20 if its a really intricate cut. Cut your decorations as quickly as possible after pulling them out of the fridge. I left a few of my mats in to long once and found out that you can freeze them too long, so its tricky. I just put mine in the fridge for about 5 minutes, that way they got a little softer, but not too soft. Also, med to high pressure at med speed. Clean your rollers out as you go. ROLL YOUR FONDANT STRAIGHT ONTO THE MAT. That is super important, thin layer of crisco, then roll the fondant and trim to the size of the mat. Sorry this is long, but I figure to much is better than to little. It took me days to figure this out lol. Hope it helps.
