If you want to try something different, why not go for a flower runner? This is essentially a grouping of flowers that runs the length of your guest tables. You can pick some really pretty colors — vibrant or muted — to create a gorgeous look.
simple long white tables with greenery table runner. P and I LOVE the look of long tables with a pop of green (and gold would be good) but overall simple. Won't have assigned seats so don't need table numbers, etc.
