have you ever done it? how do you make it not show through?? I have a request to do a chocolate cake with chocolate icing but it would force me to put white fondant on top of it to decorate with.

any ideas?

I did that once and it was fine, you just have to be really careful and make sure you roll out your fondant thick enough so it can't possible show through.

HTH!

I do it all the time--all sorts of frostings that are other than white underneath... if you can see the chocolate icing through the fondant, then you're just rolling your fondant too thin.
