How can cake icing dry quicker?

Websites recommend at least a week for thorough drying.

However, while it is best to use gum paste or royal icing which dries very hard for things like flowers or figures, if you have already made the fondant into something and you want it to dry quickly, then you can take a desk fan and have it blow onto the fondant for several hours. This will help it to dry faster. I found this information on the ehow.com website.
