Walnut shells can be used to float birthday candles in a vase of flowers.
Garlands are easy to make from a variety of materials.
Plant them in full sun in a rich, fast-draining soil. When it's time to harvest, cut some stem with each gourd so you can hang them to dry. Gourds should be stored in a cool, dry, airy place. If the gourd rattles when shaken, it's ready to be used for garden projects. Once gourds are dry, protect and preserve them with a coating of paste wax, lacquer or shellac.
