To make a rose you start by placing the tip close to the surface and beginning to squeeze. As soon as you have created a center dot, quickly and carefully begin to move in circles around it. You want to keep your circles tight, without gaps. Once you can make a rose you just repeat the process on the top of the cake until it is entirely covered.
Note: Once you are finished you can also add a ribbon or border around the bottom base of the cake. Another option you have is to do roses along the sides of the cake, but beware that they may slide down the cake if the frosting isn't stiff enough or if the cake isn't kept cool.
