wear comfortable shoes, take cash, credit cards in a small purse and be sure to take a nice bag to put your things in you buy, camera, snacks, bottle of water
you get so thirsty at the quilt show, so I carry a bottle of water with me inside my bag
pick up the business cards, and if there is something you are looking at and can't decide whether to buy it make it down on a notebook with the booth # so you can go back later if you decide to buy it
Have fun!
