Thanks Vinny. I'm going to check out a craft store today, from what I've found online, they are frequently used in quilting. I'll post if I find one, so that the Canadians know where to find them
I wanted to add that you can buy restaurant doilies (sp?) fairly cheaply, at least for use at the shows. They fit pretty well in deli cups, look nice, and have some texture so the snakes don't slide around. You can find them at restaurant or chef supply stores, and of course, I am sure you can find them online.
