IF YOU HAVE A LITTLE GIRL: On my 16th bday, my dad gave me a half heart necklace and kept half of it. My half was attached to my bouquet on my wedding day. At the reception, he surprised us by giving his half to Chris. He literally passed down the responsibility of holding on to my heart.
This is a hilarious ring bearer idea. More weddings need to have fun like this. Laughter produces more fond memories than "safe" and "typical" formal/classical weddings.
The maid of honor could put this together. Have the mother of the bride, mother in law, bridesmaids, and friends of the bride write letters to the bride, then put them in a book so she can read them while getting ready the day of. The last page can be a letter from the groom. I would totally do this if I was moh!
