Even the ribbon and paper on a valentine present can say, "I love you." Romantic poetry -- try Byron, Keats, or Shelley -- will provide words appropriate to your amorous circumstance.
Poetic Wrappings How-To
In your best script, copy a line onto 1/4-inchwide quilling paper. Or use double-faced satin ribbon, and decorate it with a short, traditional phrase, such as "Be Mine"; a stamp with adjustable letters, available from most stationers, makes the message look like that on a tiny candy heart. An old typewriter also gives a present a romantic feeling; transcribe a verse onto tinted vellum for wrapping.
If you're giving chocolates, count the ways sweetly on small paper disks, and place one beneath each candy.
