Eek! One of DH's coworkers is officially commissioning me for the baby shower cake for another coworker! She knows I'm a total beginner, and her expectations aren't overly high, but I really want to do well. Has anyone made anything similar, and have any tips for it going well? I plan to practice a ton beforehand on a cake form.

Pretty much replicating the second tier on this, except with a ribbon instead of grass. I think I'm mostly worried about it winding up not flat enough, and transportation. But I have a month and a half to practice!

ETA- Saying this is my first isn't entirely accurate. I've done a layer cake with fondant and decorations before. I've just never done one for anyone else, or for anything other than, "ooh, that sounds like fun."
