This recipe is a moth and silver fish deterrent inside your piano.
What you need
2 Bay leaves
1 tsp of Peppercorns
1 tsp Whole cloves
Small sprig of rosemary
If you are using fresh herbs then pick your flowers in the morning once the dew has dried. Lay them on a tray covered with paper towel, and leave to dry in a warm dark place.
The paper towel draws out any moisture from the foliage.
Once you have your dried ingredients, gently toss them all together and they are ready to use.
Simply place the uncovered potpourri in a container inside your piano and it will last for up to 12 months.
