Using your 'The Ruler of the Underworld' wall tapestry is easy. You can hang it indoors on your wall to add a unique touch to your room, or use it outdoors to decorate a patio or a garden area. When it comes to cleaning, just throw it in the washing machine with cold water on a gentle cycle and use a mild detergent. After that, tumble dry it on low heat. Be careful not to use hot water or a harsh detergent as it may damage the colors and fabric. Also, avoid high - heat drying to keep the tapestry in good condition.
