As you can see in the image above the table setting is using live plants, ferns and succulents to give the table an earthy feeling. Other options are to use large green napkins against a brown table cloth, again this is a cheaper option than using many live plants. You're tables and koozies don't have to be the only thing matching the colors, you can match your wedding cake too. A dark brown cake offset with light green piping and flowers is a perfect match for this color scheme.
If you do not choose to use wedding koozies as your bonbonerie, you can always give small gift boxes wrapped up with green ribbon. This helps to keep in touch with the wedding theme. The small brown and green boxes in the image above contain a trinket so that all your guests can remember your wedding day for years to come.
