Artist trading cards (ATCs) are miniature pieces of art that are traded around the world. Artists create, trade, and collect art at organized ""swap"" events, either in person or online. The only official rule for ATCs is the size: 2.5"" x 3.5"".
Strathmore’s Watercolor Artist Trading Cards feature an intermediate grade watercolor paper that is popular with watercolorists of all levels. This versatile, felt finished paper is ideal for mastering watercolor techniques or finished pieces.
