To use your Halloween wall tapestry, you can hang it on a wall in your living room, bedroom, or even outside during a Halloween party to add a spooky touch. When it comes to cleaning, simply put 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. Make sure not to use hot water or harsh detergents as they may damage the colors and fabric. Also, avoid hanging it in direct sunlight for long periods to prevent color fading. With proper care, your tapestry will last for many Halloweens to come.
