Hi, Alecia. I too was wondering about edible images. I like your shamrock idea but just to throw something completely different out there, what about a cake that looks like a mountain (An Irish mountain, of course! lol). You could have framed edible images of his bands placed around on the mountain and then him w/ a camera around his neck and his hiking boots on sitting on top of the mountain. You could put the bride up there too if you wanted. Just an idea that popped into my head when I read your post.
