Special tools for decorating (like an icing smoother) aren’t quite necessary, however, they help you achieve professional looking results.
You can use marzipan, fondant icing, icing sugar, decorative molds, fondant cutters, cake decorations to give your cake a festive touch.
Marzipan sticks easily to a moist cake, if your cake is drier one, brush the surface with some water to make it sticky.
