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. If you would like to see my collection of artist trading cards, I made a little video!
