2 parts fine Sawdust
1 part Flour
Water

To mix the clay, use a large bowl or bucket.  Mix sawdust and flour together.  (NOTE: sawdust should not contain any redwood sawdust.)  Pour in water and mix until it reaches a stiff
but 'squishy' consistency.  Add more flour if it is too crumbly.  The clay needs some kneading before the gluten in the flour becomes elastic, holding the sawdust together.  Work it in your hands or on a table top covered with newspapers.  Play with the clay a little until it becomes easy to shape.

This clay air-dries very hard. It should be placed directly in the sun, if possible.  When dry, you can sand it or not, depending upon what you like.

Use tempera or acrylic paints to decorate the finished objects.  To give your pieces a glossy coating, spray with acrylic clear finish or paint with acrylic floor wax.
