Can I use card tables or tables with folding legs?

To attract the best shoppers, we try very hard to distinguish ourselves as a place that values design.  We noticed the typical flea market or antique mall has certain items and certain displays that make it feel low end.  We prohibit those items and displays in order to maintain a coherent look and feel that embodies quality and design.  We encourage creativity in how you display your items and ask that you steer clear of any tables with folding legs.
