What would make you stop at a vendor table at a jazz festival?

I will be doing a vendor table at a jazz festival next month. I have never been to this festival and do not have a feel for the atmosphere yet so I am looking for some other opinions. What giveaways/activities would make you stop at a vendor table at a jazz festival instead of walking past it.|||a good looking vendor|||Snacks and refreshments? Artwork and jewelry?|||Good weed
