When placing a figure on a cake iced in buttercream, you should really have some gumpaste mixed in right? So it doesn't get soft from the buttercream and collapse?
The closer in contact with the buttercream that the figure is going to come the more necessary it is that the figure have been made with gumpaste (or Tylose, etc.) mixed in with the fondant. I made fondant accessories all the time for my cakes and have learned this lesson the hard way. If the figure is added right before display and a short time before cutting, then it is less of an issue. It takes a bit of time for the buttercream to break down and soften the fondant. In order to give my self a bit extra time with the item on the cake, I also try to make my fondant creations days ahead of time so that they have plenty of time to air dry and get harder. HTH
Thank you!! The reason I've been reluctant to get gumpaste was the rest usually hardens before I have a chance to use it, no matter how well I wrap it back up! I've wrapped it and vacuumed sealed it and it still dries out!
I have found that if I zap the left over fondant in the microwave for just a FEW seconds, or knead it in my hands in small quantities, it will come back to life.
