Make royal icing. Divide into portions for each color. You’ll need two portions of black (one is thicker for the outer border). Make the icing for the inner colors thinner. Dye each portion with gel food coloring. You’ll need more black and orange than the other colors. You’ll need just a small amount of white and a bit more of the lighter orange. Watching my videos will help you with getting the right consistency for the icing. Let the outer icing harden before working on the inner icing.
