Spray Starch Backgrounds by Jo. Use white or black cardstock, matte or glossy; a can of spray starch; & some kind of ink or paint: Perfect Pearls, PearEx, Glimmer Mist, Distress reinkers (use glossy cardstock with these), - anything water-based. Spray the cardstock with starch. Sprinkle or spray on the color/powder/ink SPARINGLY. (Too much produces "mud.") Spray again with starch. A variation: Crumple plastic wrap & lay over the top of the wet piece. Let dry at least 30 minutes.
