I love polka dots, but I absolutely hate the tedious process of sticking tiny bits of fondant to a cake. A few weeks ago, I visited Jessica's blog at http://jessicakesblog.blogspot.com and read about her wax paper transfer method (which I was able to use a few weeks ago to apply the Boston skyline to another graduation cake) so when I received a request for a graduation cake with polka dots, I knew that the wax paper transfer method would be the best way to go. It turned out to be very quick and simple with no need for marking the cake or measuring space between dots. Here's how it works:
First, I Googled "polka dots" and found a pattern that was spaced the way that I wanted it to be. Then I printed the pattern, cut it out to be the same height as the part of the cake that I was going to be covering with dots, and taped it to my countertop.
I am a super slow cake decorator and this took me no time at all. It also prevented me from having to measure (which I hate), or from "eyeballing" the placement of the dots... which I also hate. :-)
