I am making piggys and am trying to roll the balls of fondant or gumpaste and i just cant get it to roll into a nice ball.
Please help if there is something special I should be doing?

I put a little bit of crisco on my hands and then put a lot of pressure on the fondant and then roll super, super, fast. When I'm done, it's a perfect ball and normally there aren't any cracks in them. If there are, I just put those on the bottom so that people can't see the cracks. Hope this helps!
