Using your Lannister University 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 toss it in the washing machine. Use cold water and select the gentle cycle. Add a mild detergent to keep the colors bright. After washing, tumble dry it on low heat. Avoid using high heat as it might damage the polyester material. Also, don't use harsh chemicals when cleaning. This way, your tapestry will stay in great condition for a long time.
