Lovely Smells: Air Freshener bowls

Shelley teacup: Harebell design, demitasse cup (half size) circa 1940

I've been using this recipe for years and you can find it in various states of decay in most rooms of my house.  I originally found it in a Jackie French book.

1 cup rock salt
1 cup dried mint leaves (from tea shops, or contents of 4x peppermint tea bags)
1 cup finely grated lemon rind (dried until rubbery) You can also use orange rind
1/2 cup cloves
1/2 cup crunched up cinnamon sticks

Mix ingredients together
Keep in small bowls in the toilet, spare room and other musty places
Smells lovely, and absorbs smells
