Baby shower cake part 1

This weekend is my oldest sister's baby shower. I am one of the people making a cake for her.  I found one online but I redesigned it to fit my sister's personality and request.  I am making a two story cake with pink and white backgrounds.  The top of the smaller cake is going to have a pink and white ribbon.  The bottom one will have calla lilies all around it, the top one will have them around the base.  The cakes will have baby stuff around the middle with hearts.  The baby stuff is made out of fondant.  The calla lilies are going to take forever since I only have one calla lily maker.  I made one so far, if anyone wants to know I will put up the steps and pictures of how to make a calla lily.  The middles of the calla lilies I will make probably tuesday since I can make them all at once with the yellow sugar to enhance the middle parts.
