Using your Thunder God Sumi - e wall tapestry is a breeze. You can hang it indoors in your living room, bedroom or even outdoors on a patio. To keep it looking great, machine wash it in cold water using a gentle cycle and a mild detergent. Then tumble dry it on low heat. Avoid using harsh chemicals or bleach as they may damage the vivid colors and the fabric. Also, be careful when handling the hand - sewn edges to prevent fraying.
