Once cured, hard-shelled gourds, such as Corsican, will last indefinitely and can be painted, carved, cut, or drilled as you would do with wood for dozens of craft projects. Carve them, leave the natural color, or paint these 6"–10" round and 3½"–5" deep gourds any color you want. Gourds may be sown 24" apart if trellised.
