1 c. cornstarch
2 c. soda
1 1/4 c. water

Combine and mix together the cornstarch and soda. Add water. Heat, stirring constantly until it is the consistency of mashed potatoes. Cover with a damp towel. When cool enough to handle, knead. The material is best used for rather flat and cut-out items. It dries in the air; baking is not needed.
