So, as a basic fondant decorator, I'm confused about pattern fondant. I learned to put fondant on the cake, then stretch it to fit nice and snug. But, in concept, I would think that would ruin the pattern. Does anyone have any advice?

I roll my fondant to a size that will fit well over the cake then I use an impression mat.Carefully lay it over the cake and gently smooth it.I have never had to stretch my fondant to fit. A quilted pattern is done once the fondant is on the cake.
