For topflight drinks, make 2 slits in the center of a butterfly cutout, and then slide a straw through.
Once again my favorite white paper lanterns used in another fun way this time from Martha Stewart's website: Let a flock of colorful paper butterflies loose, and you'll instantly give party decorations a lift. Trace the template onto a folded piece of paper, cut out the shape, and unfold the wings. (For different sizes, photocopy the template, reducing or enlarging the image.) Attach some to paper lanterns with tape or glue dots (sold by the roll at crafts stores), then fold the wings upward for true-to-life flutter form.
