Share a little about the materials, processes, and techniques used to create this cake Used Buttercream on white cake. Wilton tip 104 for roses then used different tips for borders to create different effects. What are you most proud of? This is the smoothest I have EVER been able to get my buttercream! What advice would you give someone starting this project? Start early enough that you are not up until 4am to finish it. Really though the trick would be to know what you are going to do before you start & I didn't.
