Hi, I'm making an owl cake topper out of modelling chocolate for a birthday cake so far (without any decorations) it weighs 10.6 oz and is over 3 inches high. My cake will be a tapered square cake and 7 1/2 inches on top. How do you think I support the owl? The cake will be covered in fondant. Do you think toothpicks will be enough or do I need to use a couple of doughs in the cake and stick through the owl?
