Aspirin, tissues, paper towels, camera (take a picture of your booth after its set up); cooler with soda and water; small snacks; comfortable shoes; cell phone; chair cushion; deodorant; extra socks; jacket or sweater; sunscreen; water bottle; wet wipes; and extra change of clothes (you never know what could happen) and a GREAT attitude. I also recommend buying an inexpensive canvas apron and sewing or fashioning some pockets that can be Velcro’d shut to put your money in.
