Whether you're a professional pastry chef or a beginner to cake decorations, this set of 6 piping nozzles will help to create gorgeous buttercream flowers with little effort. Just fill the piping back with the buttercream of your choice, hold the nozzle just above the surface of your cake or cupcake, pipe gently and once the buttercream makes contact with the surface, pull the piping back up until you get the desired height.
