Tie a piece of dental floss to the ends of each flower or bouquet. Hang up your flowers by tying the dental floss to a hanger. Hang your flowers on a door hook in your basement for 2-3 weeks. Remove the dried flowers when they feel hard and crispy.
Cut a piece of dental floss about 1216in (3041cm) long. Secure the piece of dental floss to the stem of an individual flower. Additionally, you can wrap a rubber band around a small bouquet of 3-6 flowers, and then tie the dental floss to the ends of the bouquet. If you don't have dental floss, you can use twine instead. Make 2-3 knots so the floss stays in place. Once your floss is tied around your flower or bouquet, tie the other end around the bottom, vertical bar of the hanger. Tie 2-3 basic knots so the dental floss stays put. Hang each of your flowers along the bottom of the same hanger until you run out of space. For instance, secure 3 bouquets of 4 flowers to the bottom of 1 hanger. Put the hanger on a hook hanging from your door so they can dry completely. You can store your flowers in any clean, dry, well-ventilated space that gets particularly dark. If your flowers are exposed to sunlight, they will not dry entirely. After several weeks, your flowers will dry up completely, which is necessary when preserving with hairspray. They will lose pigment and shrink up a little once they're dry. The petals will be crispy and break off easily, so handle them carefully!
