I have been using dishes of candy to lure people into my booth for a while now, and it really works! I often use brightly colored candies in a cute vintage dish. I put a little pink serving spoon in the dish, and people come back repeatedly to visit for more. Whether they buy something or not, that's fine - at least they are viewing my work for a second while they munch.
I wanted to feature some candy ideas for you to use, let me know if this works or you have an opinion on the matter :)
