Harvest the lavender (if necessary) in the early morning when the plant's essential oils are most concentrated. Grasp a handful of the plant's longest flowering stems and cut them off from the plant as close to the plant's main stem as possible.
Tie the ends of the flowering stems together with a rubber band or garden twine. Hang the flowers in a cool, dry room for three to four weeks until the foliage and flowers are dry and crisp to the touch.
Stuff a paper bag or cloth bag with the dried lavender. Use a bag big enough to comfortably fit in your laundry drawers.
Fold the end of the bag over and secure it shut with a clothespin. This allows you to easily open the bag and replace the lavender once its natural scent is spent.
Place the bags in your laundry drawers, laundry baskets and anywhere you want a fresh, lavender scent.
