To use your Plumber Boy wall tapestry, you can hang it on your wall either indoors or outdoors to add a touch of style. When it gets dirty, machine wash it in cold water using the gentle cycle and a mild detergent. Then, tumble dry it on low heat. Make sure not to use hot water or a harsh detergent as it might damage the tapestry. Also, avoid hanging it in direct sunlight for long periods to prevent color fading.
