Everyone's dressing up for the wedding - and that includes your chairs! Are you renting chair covers? Using any chair sashes? Are you using them to bring your color scheme into your decor, or are you masking some chairs that have seen better days? What will they look like when they're all done? How will your sashed be tied?
Who's going for a subtle touch of color?
Who's going bold and blingy?
Who is going formal?
