You guys are being super helpful; thanks! Here are some pictures.
What about something like this (but NO MUSHROOMS! Mushrooms and cake do NOT go together! And I'm someone who likes mushrooms!)
I love the shape of the yellow cake on the right. But I don't know how it would look in buttercream.
I like the size of this one. But clay, like mushrooms, should not be in proximity to cake, in my opinion. (Because I always have one. An opinion, that is.)
I don't know what's going on with the newspaper here...but this cute two-toned cake is almost making me rethink my "gahh I have enough to think about. Let's just have a simple white cake!" stance.
Here's that pink cake that made me super wistful...but pink is not really a part of our wedding (saving that for Erika's).
At the end of the day, I'm also considering a two or three tier version of this, sans candles. But I guess you'll just have to be surprised! And ... maybe I will too. Hey Mom, can I just write you a blank check? :-D
