I'm wondering how non-traditional I can go on the cake before it starts to look tacky. My FI proposed in the Grand Canyon, so we thought, how cool would it be to have a cake in the shape of the Canyon: each side of the canyon, the river below, and the overlook where he proposed. We could put the B&G figures where he proposed. I'd leave the logistics to the baker, but I think it could be done. If you went to a wedding and saw that kind of cake there, would you think it was tacky or delightfully unique?
