Hi I want to practice sculpting 3d cakes, but I don't want to waste a lot of cake or rice crispy treats while doing it. PLEASE! Are there any suggestions?!!! :rollAlso has anyone made a 3d panther cake? I would like to surprise my son's football team with a cake and thought it would ne cool to have a full sized panther cake as this is their mascot. As you can see I have great ambitions, lol. All help and suggestions are welcome. THANKS!!!
