I need advice..going to a craft faire selling my ACEOs anyone who has done

I need some help and advice I am going to a craft fair next month and will be selling my aceos. Could you give me some advice about explaining what they are in a display, how to display them, pricing, any advice would be very appreciated. I have sold jewelry at craft fairs but this is the first time I will have tried to sell my art cards. So many people do not know about them that I feel like I have to do some education first.
