I don't do fondant cakes yet,but  I made fondant roses in a mold that I want to put all over buttercream cake. If my buttercream is stiff and crusts well do you think it can handle the fondant roses and leaves, or do you think they would slide down from the weigh?

 This is similar to what I want to do on a buttercream cake. I did not make this cake,but I love the way it looks. I hope I don't get in trouble for reposting it.

I found my answer on an old thread. Thanks.
