Making roses and was just was wondering which is better fondant or gumpaste?
I prefer gumpaste. They dry faster and harder than ones made from fondant. If you're just starting out making them, I would do them in fondant first - it will give you more working time. Gumpaste can dry out while you're working with it making it difficult to make flowers from. Some people prefer a 50/50 mix of fondant and gumpaste.
I have found that those made from 100% gumpaste resist humidity more than fondant or 50/50 ones will. That being said, humidity can affect gumpaste flowers also.
