This is an awesome groomsmen gift!
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!
