To use this Jurassic Summer School wall tapestry, you can hang it on your wall either indoors or outdoors to add a touch of style. When it gets dirty, just toss it in the washing machine. Use cold water and set it to a gentle cycle, then add some mild detergent. After the wash, put it in the dryer on low heat. Avoid using harsh chemicals or bleach as it may damage the vivid colors and the fabric. Also, be careful not to overload the washing machine to ensure a thorough clean.
