Step one: Save your milk or juice carton from your school lunch. Rinse it out and take it home.
Step two: Cut out pictures from old magazines and paste them onto the outside of the milk carton to decorate it.
Step three: Put dry potting soil into the carton. Fill it about one-third of the way, and drop in your favorite flower or plant seeds.
Step four: Stick a straw that would otherwise go to a landfill into the soil to give your plant something to grow on.
Step five: Staple the top closed, but leave the straw sticking out.
Step six: Make a card from paper that you would otherwise recycle to go along with your potted plant.
