I am doing a local outside fair in September and making dummy cakes for examples. What can i put on the fondant to keep it from getting eaten by bees? Spray shellac? Also i wanted to do one with ombre buttercream (made with shortening and powdered sugar) rosettes. These are just example cakes and i will tossing after. Any advise would be helpful! I also plan to have out samples of my cakes.

Use Wilton's fondant, any cheap brand or make your own? Do not add any flavoring.  That's what I hav done but then my fair was not outside - just in an UNconditioned building w/open doors - no windows.  B'cream made w/nothing more than sugar & shortening should be fine.....again I've done it for yrs.

thank you!!
