Does anyone know what mold was used on this bottom tier? I can't seem to find anything like it!
It looks like a fluer de lis (I'm sure I butchered that spelling). Marvelous Molds sells these types of molds. They've got a lot of really cool molds. http://www.makeyourownmolds.com/marvelous-molds/fleur-de-lis It may not be exactly like that one, but you can see what they've got and if any of them will work for you.
Or you can buy a make your own mold kit and create one of your own.
Thank you for the link to the website! I will definitely be looking!
