Using the sash is easy. Just drape it over your shoulders during the graduation ceremony. It'll instantly make you stand out. When it comes to cleaning, it's best to spot - clean with a mild detergent and cool water. Avoid using harsh chemicals or putting it in the dryer. Also, store it in a cool, dry place to keep it looking its best. Don't worry about wrinkles; you can gently iron it on a low - heat setting.
