Cheap "air freshener"

Use spices to make the air in your home smell better. Ok,. that's obvious... but how? Put them in a bowl of water and set them where the sun will shine on them, or use an electric or candle powered simmer pot with a little water and some cinnamon, caraway, rosemary, cloves or whatever has a smell that you enjoy. You can make your own air freshener to spray in the air, too, by using water that's had spices or other smelly things simmered in it.
