Mitch Lyons has done this for years. i know he is on youtube showing how it is done. he did a demo for our guild meeting a few months ago. the fabric he uses is a heavy grade of brand name Pellon. it is sold in fabric stores for lining jacket lapels and other stiffer items of clothing made by seamstresses or tailors.
he has laid down a very thick "sheet" of clay onto which he puts various colors of slip. once he is satisfied he puts the pellon on top and rolls the color into the pellon. the resulting print is then framed. watch the trick of the mat around the edge in the video.
