When I roll a ball of gum paste, there is almost always a crack.  I don't have any problems with small balls but the larger the ball the bigger the problem gets.  I have rolled over and over between my palms but I can't get the ball completely smooth.  Any suggestions?

AWhen that happens there is not much you can do except re-knead it to get it warmed up and pliable (or put it in the microwave for a few seconds then knead), and start your ball again. If the problem persists, try adding a little Crisco to the paste.

I put mine in the microwave as Dayti suggested. It always works and once it cools down it dries faster.

Thank you for the responses.  I have rekneaded and used shortening but doesn't seem to help.  I will try the microwave too.  Thanks again.

AI have found that the larger fondant balls require a lot more pressure than the smaller balls to avoid cracks.

AI can't remember who did a video tutorial on this, and not sure if I can explain with text.... I make my ball, maybe a tiny bit bigger than I need, then work it like everyone else has explained. With any cracks left after that I keep working/pulling that crack toward the bottom of the ball until eventually you have a tail that you keep pulling and smoothing till it breaks off. Then roll it around to make it round again. Maybe someone knows of this method and can explain better.
