So my bakery is amazing and made us a whole 12" round cake for free just so we could try the fondant. As cute as it was, we definitely decided on no fondant. I had really only looked at fondant cakes, though, since we aren't putting floral on our cake and our colors aren't in our topper at all.
I'm seeing some cute things while searching, but if you had a cake with just a buttercream finish, I'd love to see it to see what we can possibly do that's at least a little interesting/incorporates your colors!
