I was asked to do a cake with Foofa from Yo Gabba Gabba for a little girl's 3rd birthday. I was excited to design a cute cake, and my kids were equally excited when they saw the Foofa that I created for the first time.
Although gumpaste may seem like the same thing as fondant, it is very different. Gumpaste dries hard, almost like glass. It will shatter if dropped after it is completely dry. Fondant will get stiffer, but will not harden completely. You would never want to cover a cake with gumpaste. It is really great for delicate flower work, straps for handbags, 3D figures, shoes. It is perfect for something that you want to maintain a specific shape. It requires time to dry as well. I like to let gumpaste decorations dry over night. If you are interested in learning how to decorate with fondant or gumpaste, don't be afraid. Pick some up at the store and play with it like you did with playdoh as a child. It's fun!
