How does this work? Is it as easy as I think....? Someone is wanting a Star wars cake and I thought this might be quick and easy but I have never done it.....

Welcome to cake central ! Yes they are super simple ! after you have your Image ( you have a printer or have it made ?) After your cake is iced and smoothed but not crusted you just peel the Image off of its backing and lay it on the cake top. You do have to get it in the right spot the first time because you really can not move it . Then you can add a border around it or not and finish decorating your cake! Sometimes the Image can be stubborn and doesent want to come off the backing but if you stick it in the freezer for about 1-2 mins it will pop right off ! Thats about it !!
