Message in a Bottle Invitations
Lure guests from their homes with messages in apothecary-style bottles. The paper owes its decrepit look not to years in a crypt but to being dyed with tea. Send the bottles in mailing tubes with a few pieces of raffia for cushioning.

If desired, take this extra step to make these invitations look authentically old: Brew strong black tea; let cool. Pour it into a plastic bin. Soak uncoated 8 1/2-by-11-inch paper in the tea for 1 to 2 hours. Remove it, and let dry completely on paper towels.
Print invitation template directly onto the dyed paper.
