Given the date for the show, you will attract a lot of Christmas shoppers looking for gifts. It really does depend on the location, but most folks are looking for something on the less expensive end of the scale, so the pot holders are a good idea. There are some good ideas in this recent post:

I would also look into getting something for your table that will add height to your display, and maximize your "sales area". Maybe a small set of book shelves... with the iPods being so popular, there are lots of CD racks at resale shops. These would be perfect for small items. Or if you have one of those cup holders, you could display your pot holders.
