•Very easy to build; tidy for indoor use •Plastic bins keep compost moist-Will require regular additions of dry bedding •$6 - $20 for new materials. Materials (1) Plastic storage container with a tight fitting lid - 12" to 18" tall, 12"x24" base. You can purchase this item at any Wal-Mart Store Tools Power drill (1/4" bit) or 2 1/4 hole saw. .  Please make sure that this part of the process is supervised by and adult!

Assembly For indoor use, drill several holes for ventilation about halfway up the sides of the bin. For outdoor use, holes can be drilled in the bottom for ventilation and drainage. I have also used a hole saw to drill larger holes. You can use plastic window screening glued to the bin to keep flies and other pests out of the bin.

(Rinse the bin before placing the bedding in it. Some of the soft plastic containers will leech chemicals if they are not cleaned well before use.)
