Using these chair sashes is a breeze. Simply wrap them around the back of your banquet - style chairs. Make sure the chair back is no wider than 17 inches to ensure a proper fit. When it comes to care, you can throw them in the washing machine for a quick clean. Then, tumble dry on low heat. Just remember, this set only includes the sashes, so if you want sash buckles, you'll need to buy them separately. These sashes are great for adding a touch of elegance to weddings, parties, and other events. Enjoy using them to decorate your special occasions!
