One way to make salt dough is to mix 1 cup of flour with 1 cup of salt, and add water until you achieve the desired consistency. Another method includes mixing 4 cups of flour with 1 cup of salt and stirring in 1 1/2 cups of water.
Gradually adding water to the salt and flour mixture keeps the dough from becoming sticky and difficult to work with. Knead the dough on a floured surface until it becomes stretchy and smooth. Roll the dough into a 1/2-inch layer, and use cookie cutters of various sizes to cut out Christmas-themed shapes, such as trees, stars, snowmen and wreaths.
Insert a toothpick or plastic straw through the dough to configure a hole for the hanging ribbon. Arrange the dough ornaments on a baking sheet covered with parchment paper. Baking them slowly at 100 degrees for up to 3 hours allows for thorough drying. When they are finished, decorate the cooled ornaments with acrylic paints, glitter, buttons and beads.
You can also add creative touches to the salt dough ornaments by cutting out small holes for a lacy effect or inserting colorful glass beads before baking. Construct a garland by spacing ornaments a few inches apart and tying them together with narrow ribbon.
