I'm doing my first multi-tier wedding cake, covered in crusting buttercream. I will be adding lace appliques to each tier. I have several questions:
1. Is it best to use fondant, gum paste, a 50/50 mix, candy clay, or marzipan on a buttercream frosting?
2. How far in advance can I make these appliques and how should they be stored?
3. Should the cake(s) be at room temp to apply the appliques?
4. How far in advance of the wedding can I apply the appliques?
