Using these chair sashes is easy. Just wrap them around your folding or banquet style chairs and you're all set to add a touch of elegance to your event. Here are some things to keep in mind. Don't try to over - stretch the sashes more than the maximum stretch of 16 feet as it may damage them. When it comes to maintenance, you can simply throw them in the washing machine. Then tumble dry on low heat. This will keep them looking their best for your next event.
