1. If you're using an oil base, you will want to use 30% essential oil to 70% base oil. You can experiment with the percentages to see what works best for you.
2. If you're using the vodka and water mixture, you will want to add approximately 12 drops of essential oils with 1/4 cup of water then add a little of vodka (the vodka helps bind the oils to the water).
3. Pour the mixture into your receptacle and place one end of the reeds or skewers into the solution, allowing it to saturate the reeds. Then take them out, and place the opposite ends into the bottle. You will want to rotate which ends are in the scent solution about once a week.
