The Materials: Paper. Paper serves as a "bedding" for the worms to live in. The worms consume it along with the other materials. You could use any kind of paper, but worms will consume newspaper, cardboard, paper towels, and other coarse papers faster than fine printing and writing papers.
Food Scraps. Almost any fruit, grain, or vegetable material other than oil is good for worm composting. Egg shells, coffee grounds, and tea bags are also fine.
Other materials. Add a little soil or fine sand to provide grit. Leaves and other yard trimmings can be used as part of the bedding. Live-stock manure is excellent food for worms in outdoor containers.
