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 hope my bridesmaids are this awesome
For MOH duty: Have each bridesmaid, mother, mother-in-law, aunts, etc... create a scrapbook page which includes a letter to the bride along with pictures. This is something she can read while she gets ready.
