How about getting a HUGE bottle of wine or champagne that everyone at the bridal shower can sign? Then the bride can take it with her on her honeymoon!
Another wedding idea that could be adapted to a bridal shower. Gosh, would any of us know how to use a typewriter?? Love the idea of wedding guests typing a message to the bride and groom on a vintage typewriter. I have that OLD coooool black one you could use, I just would have to get an ink wheel.
Memory Jar: What a great way to share your memories with the bride!
Irish Marriage Prayer. Just lovely =)
