Can I make star shaped flowers from powdered sugar frosting and let them dry to put on my cake? - star shaped cake template

I accept this point of the star by the crowd and make flowers with powdered sugar glaze. Let it dry, so it can without breaking grip, then put on top of each slice of cake, I make the task it was. Is it possible they have for this type of meringue? How early can they do? How long does it take to dry? As stores do?
