Will a fondant bow last 2 weeks, and if so how and were do i store it? If it does not then whats the best time to make it?

A fondant bow will last way longer than two weeks. When storing it dont put it in an air tight container because the fondant can begin to soften. I would losely wrap it with saran wrap and place it on a container with out a lid. This will protect it from dust and keep it from being bumped. Good luck!
