Has anyone had any luck mixing candy clay with other fondants besides Pettinice like marshmallow fondant or Satin Ice?

Someone, anyone?

I have only used pettinice sorry. I have heard that Michele Foster's white chocolate fondant recipe uses white chocolate (which is the main ingredient of candy clay), so I guess it is successful. Why not just try mixing some in and see how you go?

I mix wilton's fondant and candy clay- no problems.
