I have been asked to make a tiered wedding cake iced in buttercream with leaf and flower appliques. The appliques have a 3D look and will cover most of the cake. I thought of making the appliques out of gumpaste but wonder if that might be too hard. Could I make them part fondant and part gumpaste? If so, how much of each? If I put the cake in the frig( bc of the buttercream) will this affect the appliques?
I hope this makes sense, I tried to attach a picture but can't get it to upload.
Thanks everyone, I really appreciate your help

What is it about the cake that needs to be refirgerated?

Just worried about the weather here in New Orleans and transport of the cake, Thought I'd store the cake in the frig to be sure it was solid

If you do want to refrigerate it, just make sure it comes up to room temp and the fondant has a chance to dry out (sometimes it is a little sticky) before you transport. That might defeat the purpose of chilling it in the first place though.
