Craft paint can be made by mixing ½ cup corn starch with ½ cup cold water. Separately, soak ¼ oz (1 packet) of unflavored gelatin in ½ cup of cold water to soften. Pour the starch mixture into 2 cups of hot water, and slowly stir in the gelatin. Finally, for each cup of the mixture, add ½ cup of soap powder or grated soap and 1 tsp. of Rit dye.
