This is absolutely interesting. I've learned to make gum paste flower, I learned to the technique of covering the the cake with fondant..and I have done a few one tier fondant cake. but unfortunately I have no chance to learn to assemble three tier wedding cake but I have to do so after much persuasion from my friend who want me to do her daughter wedding cake. Well leaving me no choice...I took up the challenge and tried. Guess what? How do I made it...my goodness I relied total on youtube. Interesting the show the step how to structure the wedding..wow..it's amazing and its simple...never that i thought by observing I now can make three tier wedding cake. This was my first and I am happy with the result.
I decorated the top layer with "peony" second and third layer with briar rose, blossom and stephonatis flower..for every layer I puy a ribbon. Simple design...but it was great as a first timer
