Random, I know, but I signed up for a booth at my local Wiener Dog Races 2010. I'm going to sell Wiener Dog themed crafts. This will be my first craft show. Any advice for me? The organizers told me about 200 people attended last year, but they expect even more this year, since "a guy will be bringing about 40 wiener dog owners from [Southwest Montana]." How much should I make/bring?
