Artist trading cards are made to be traded, never ever sold. Even smaller than an index card, just as risk-free, just as full of potential. The dimensions are 2.5 x 3.5" or the size of a playing card. Create collages, cut watercolor paper to size and splash paint, stitch around the edges and put a quote inside, make a collaged person with scrapbook paper, layer papers with words on top. The prompt is to create three artist trading cards.
