I am making a cake for my cousin's wedding this weekend. It will be two-tiered. 6-in and 8-in. The bottom tier is a dummy. I got FondX and used THE MAT to roll it out, which works really well. The only problem was after I got it on the dummy there were little tiny "craters" everywhere like there had been bubbles there and I don't know why? Should I have kneaded some Crisco into it or something? 

HELP! 

I use Fondx 99% of the time.   The only thing I can think of is you didn't knead it enough.   I never have to add any crisco.  I am a huge Fondx fan. 

Thanks so much! I will do that next time! 

I think rolling the fondant on The Mat is what caused the craters.  I have seen other posts where people have said the same thing happened to them.  I have also seen pictures of the fondant on cakes with the little craters.

AThank you so much! I think I'll try rolling and covering the top tier without the mat. I didn't even think about that being the problem!
