Use this dye to create photograms, continuous tone photographs, shadow prints and ombres on fabric and paper. It is also great for painting, tie-dyeing, screen-printing, stamping or batik. Simply apply to fabric or paper using a brush, sponge or brayer - while still damp, expose the design to sunlight and watch the color magically appear. Place objects on a coated substrate to block development during exposure; any object that casts a shadow will create a pattern. After image exposure, wash out the undeveloped dye with SolarFast Wash and hot water.Details:Black8 fl. oz.
