To use your Halloween wall tapestry, you can hang it on a wall inside your home to add a spooky touch to your decor, or outside during a Halloween party. When it comes to cleaning, just toss it in the washing machine with cold water on a gentle cycle. Use a mild detergent. After washing, tumble dry it on low heat. Be careful not to use hot water or a high - heat setting for drying as it may damage the fabric or cause the colors to fade. Also, avoid using harsh chemicals on the tapestry to keep its vivid colors and crisp lines looking great for a long time.
