Create beautiful, expressive art with rubbing plates! "Line" is a fundamental building block of art. We've created 12 line-patterns. Lay a sheet of paper over top of the plate, rub with the side of a crayon to reveal the pattern. Cut the paper into shapes to make wild collage art or cut into strips to make paper sculptures. Check out our instructional video for suggestions. Each pack includes 12 Plates, 8" x 8-1/2" (20 x 21 cm).
