Pardon the "busyness" of the picture, but this was my table (front and almost-center as you walk into the town hall) at my first arts festival.
If I'm going to participate in these sorts of things, I do need to invest in display racks (such as the one on the left side of my table). I think it might be too kitschy asking people to page through notecards displayed in wicker baskets. Or, is it unique and less commercial? I guess the sales will speak for themselves.
