Strathmore's Smooth Art Board is an acid-free multi-media board, specially sized for sketching, drawing, painting or printing, and it is more than heavy enough to use for mounting. The same great surface paper is mounted to both sides of the board so that both sides are usable. They are a beautiful bright white and measure an impressive 1/16 of an inch thick. The core of the Art Board is also white. Coat with gesso first to use with oils. Available in packages of 10 and 20 ready to use cards, perfectly sized for ATCs, ACEOs or Sketch Cards. (2-1/2 inches by 3-1/2 inches).
