Using your 'Way of the Ninja' wall tapestry is easy. You can hang it indoors on your wall to decorate your room or put it outside to add a special touch. When it gets dirty, just pop it in the washing machine. Use cold water and a gentle cycle, along with mild detergent. Then, tumble dry it on low heat. Be careful not to use hot water or a harsh cycle, as it might damage the tapestry. This way, your tapestry will stay in great shape for a long time.
