In a medium saucepan, mix salt and 1/3 cup water over medium-high heat, stirring occasionally until mixture begins to boil. Stir an additional 30 sections and remove from heat, immediately adding Clabber Girl Corn Starch and 1/4 cup cold water. Add a few drops of food coloring if you desire color in the clay. The mixture will resemble mashed potatoes. Stir till mixture thickens, cool, then knead on a board or counter top that has been lightly dusted with Clabber Girl Corn Starch.
Roll out as dough to desired thickness for ornaments (about 1/4-inch thickness). Cut with cookie cutters into desired shapes and let dry. If you wish to paint the ornaments, it is best to do this when they have dried completely or the paint color may spread unevenly. Store unused play clay in a refrigerator in a sealed container with a damp sponge.
