To use your 'Decaying Dreams' wall tapestry, you can hang it indoors on your bedroom or living room wall to add a touch of style, or use it outdoors for a picnic or to decorate your patio. When it comes to cleaning, just toss it in the washing machine with cold water on a gentle cycle and use a mild detergent. Then, tumble dry it on low heat. Avoid using bleach or harsh chemicals as they may damage the colors and fabric. Also, don't wring the tapestry forcefully when wet to prevent any damage to the hand - sewn edges.
