I dont usually work with findant....and i am trying to make a nemo cake. I figured fondant for the fins, tail and small pieces...but i cant seem to get teh fondant to harden so it will stay up for the tail. I need help here, and i need it fast... PLEASE give me ideas, and tell me what I may not be doing to make it stand up.... THANK YOU!!

You should use either fondant with tylose powder (which will help it harden), gumpaste, or a 50/50 fondant and gumpaste mix. hth

Fondant will harden on it's own but it takes a few days to dry. I've made flowers using just fondant and let them dry hard before applying to my cake. If you don't have time to let it dry on it's own then you do have to add tylose or gum paste.
