My VERY FIRST try at cake decorating! Thanks so much for all the great inspirations (from posted photos & chats)! Lightning McQueen is royal icing transfer. Broke in 3 pieces (can see the repair job). Did it break because not enough time to dry? Would love to hear advise. This cake is for friend's son's birthday. Practicing for my daughter's in 3 months and my son's birthday (same theme) next March.
