Use ivy, eucalyptus, boxwood and evergreen can be easily wired to create a wreath which wraps around the lower part of the lights. Into this hide floral vials so only the stems and flowers show. This can be a great way to free up table space or coordinate with flowers below for an extra extravagant party. Similar to the hint above consider using grapevine in lieu of a green wreath and add pine cones and dried flowers, pheasant feathers and a seasonal holiday wired ribbon. This can be used from fall through Christmas with a simple change of ribbon.
Wired ribbon has a multitude of uses.
I like to keep a few rolls around just in case my table needs that extra dash. Some of my favorite uses- tie napkins with generous bows. Unfurl and spill around flowers or cluster about candlesticks. Make a nicely formed bow and write name on tail in lieu of place cards. Add loops to a flower arrangement to pull out a desired color.
