How many days in advance do you need to make fondant stars?

You can make fondant stars 1 to 2 days in advance to allow them sufficient time to dry and harden. This drying period helps them maintain their shape and ensures they are sturdy for decoration. If you're using them for a specific event, preparing them a few days ahead can also alleviate last-minute stress. Just store them in a cool, dry place until you're ready to use them.
