To use this table overlay, simply place it on top of your square table. It's perfect for adding a touch of elegance to special events like parties or dinners. When it comes to cleaning, you can gently spot - clean the sequined areas with a mild detergent. Avoid using harsh chemicals as they may damage the sequins. For storage, fold it neatly and keep it in a dry place away from direct sunlight to prevent color fading. If the overlay gets wrinkled, you can use a steamer on a low setting to smooth it out.
