One place that I found was Chandler's Cake & Candy Supplies in Concord.
Chandler's is run by a woman who is knowledgeable and kind. I have made at least 3 trips into her store for supplies and advice just for this cake. She has been extraordinary!
She is the queen of fondant and took the time to answer my questions. All my questions!
In addition to almost every cake supply, she carries baking supplies, tools and a fantastic array of cookie cutters! She even rents out cake pans!
I promised I would bring her a picture of M's cake when it is all done!
