Wooden lanterns can be used both indoors and outdoors, depending on their design and the materials used. For outdoor use, choose woods that are weather-resistant or have been treated with protective coatings. Indoors, almost any wooden lantern will work as long as the wood is dry and not exposed to excessive humidity. Make sure the lantern is placed on a stable surface or hung securely to prevent tipping over. Consider using LED candles for added safety, especially in enclosed spaces.
