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.
