Whilst many people still opt for hiring chair sashes I love the fact that more and more people are looking at more individual ways to decorate chairbacks. Perhaps you want something quite simple and I love the idea of using a very wide satin ribbon or fabric sash to tie to the top of a ladder back chair, with large loops hanging down the back of the chair. However flowers are proving popular to deocrate chairs and you could opt for a single bloom, sunflowers look fabulous on their own tied with raffia to the back of a chair. Yet you could make small posies to tie to the chair with lace or ribbon. A more eclectic option is to have a collection of different chair styles in different colours, which wouldn't need decorating as they would be statement enough on their own.
