Using your Pretty Cult's Crystal Witch wall tapestry is a breeze. If you want to use it as a wall decoration, simply hang it up using the grommets in each corner. You can use nails or wall hooks for this. For a picnic, just spread it out on the grass and enjoy your time outdoors. When it comes to maintenance, it's best to spot - clean it with a mild detergent if there are any stains. Avoid using harsh chemicals as they may damage the fabric. Also, don't wring it out when wet, just gently squeeze out the excess water. If you need to store it, fold it neatly and keep it in a dry place away from direct sunlight to prevent fading.
