Dagnammit, I was afraid of that. I'll have to order them in 100s then... it's just a huge expense starting out, when I'm not sure I'll even get the business. Maybe I'll see if I can get a few boxes from somewhere to start off with, in just one size, and only make cakes that will fit the boxes for now!
Can you go to a local cake supply store and get just a few? That is what I do.
