Just to prove that going green doesn't require special equipment (but does require a sense of humor), here are some out-of-the-ordinary uses for ordinary plastic bags that have already served their original purpose.
Kneepads - to protect your clothes when kneeling in the garden or on a dirty floor, tie a plastic bag around each knee.
Gloves - we love our pets, but there are some things no one wants to touch. Use a plastic bag on each hand during clean-ups.
Umbrella cover - a wet umbrella can make a mess of your floor, your car or your purse. Cover it with a plastic bag until you have time to set it out to dry.
Counter cover - protect your counter from meat juice by spreading a plastic bag under the package, or peel your vegetables directly into a plastic bag for easy disposal.
Slipper covers - the paper is at the end of the driveway, you're in your robe and slippers and it's raining. No problem; put a plastic bag on each foot and your slippers will stay dry while you retrieve the paper.
Pot filler - large planters full of dirt can be too heavy to lift. Try putting some crumpled plastic bags at the bottom of the pot for lightweight filler.
