When hosting an end of Summer barbecue, keep the look fresh and light. Start by covering the table with a plaid khaki tablecloth. Glass plates that resemble classic paper plates are whimsical and fun. Red cloth napkins add a punch of color to the tablescape. Serve the mixed meat and veggies on large oval platters. Pour the cocktails into highball glasses. Light candles and place potted plants near the table. Arrange the s'more-making ingredients in wicker serving baskets and tie the marshmallow forks (or twigs) together with a bow.
