i made a wedding cake and the fondant wrinkled on the rolling pin as i was lifting it. i could not get the wrinkles out with anything! it all went well, i just covered it with the fresh flowers i was asked to put on the cake, but i want to avoid this problem in the future to save my sanity!!!
when the fondant gets a bit dry and then it is moved, it has the tendency to get wrinkled or looking like elephant skin. Try rubbing some shortening on it to get it moist again. I know its really annoying, it happens to me too. Working fast may also help so the fondant won't crust as much.
