Here's a charming way to help guests at a large party keep track of their wineglasses: Give each a name tag.
Martha Stewart Living, November 2002
You can make wine tags out of construction paper with leaf-shaped punches (available at crafts stores), or cut your own with scissors. Write names on tags, and use a 1/8-inch hole punch to make small holes. Thread waxed twine through holes; knot around glass stems.
