i'm a newbie and i'm wanting to put drapes of fondant on the side of a cake and i want them to be level and even. So, can someone give me detailed instructions on using the cake dividing wheel? for example, if you are wanting to divide a 6" cake into 6ths. do you put the cake in the center and just mark everywhere the 6 is on the wheel? do you line it up exactly on that # or do you mark it where the line is in corilation to the #?
