When you have a vase of flowers that are starting to die, you can dry them out, add oils, and make potpourri.
Step One: Dry the flowers by hanging them upside down. A fun way is by hanging them from a ceiling fan.
Step Two: Pick a fragrance by mixing oils (some good choices are floral, citrus, herbal, or spicy).
Step Three: Before adding the flowers to the oil, add chopped orris root to the oils (they hold the scent better than the flowers). Then add the leaves and pedals.
Step Four: Shake concoction once a day for 3 weeks. After the 3 weeks, it should smell delightful!
