Hi, your cake and the figure is fantastic. Have you done the figure with fondant or gumpaste? If its gumpaste, you need to put it in an airtight box and have to keep away from direct sunlight. I still have some of my figures, which I made few years ago.
Elvis is made out of fondant...I have never tried to work with gum paste before, and just recently started with fondant.
I haven't done any of my figures with fondant alone. Sorry I'm not a big help. See what other members suggesions are.
I've heard you can save your figures, but I think they have to be done in gumpaste.
I have a question....if you get BC on your figures, how do you get it off so you can preserve your figures or is there no hope and you have to throw them away.
You could shellac (varnish) it if you wanted with confectioners glaze.
Should keep for a good while as is though!
To get any b'cream off the figure, just wipe gently with paper towels.
To keep allow it to dry for several weeks. Then put a glass or clear plastic jar or such over it and keep it out of sunlight and moisture.
