Hi, Faith! My piece of advice is if you are not experienced in medium – big sized cakes, it is in your and your friend’s best interest, to let this enterprise to some baker who has the expertise. I think that for your friend, it is her wedding, a memorable and unique event, where evething should go on the bright side. Frankly say so to you friend, she will surely understand your sincerity. You will have plenty of opportunities to practice cake decor, so you would feel safer for the results. Again, it is what I would do in your place. Good luck!! Silvia
