Can you pre make fondant decorations?
Sugarpaste /Fondant models & other decorations? These you’d want to make at least 24-48 hours in advance but again if stored correctly (as per domed toppers) you could make them months in advance.
How do you dry fondant decorations?
Moving air around fondant gets the drying process going. Place fondant pieces on a cookie sheet lined with parchment or waxed paper, then set the sheet in front of a stationary fan. It’ll still take a few hours (up to overnight) to dry your fondant pieces, but the overall time will be shorter.
