Two things I got that I loved and since then I've given as gifts to close friends or family that everyone loves are:
1. A Marriage Blessing Book
I got mine at the rehearsal dinner. Beforehand you send out a note to friends and family, usually close relatives and close friends, to send you a blessing for the couple. It can be something they wrote personally, or a poem, or scripture or anything special a/b the couple or individual (since not everyone will know both the groom and bride). Then you make each blessing on a page and then into a book. It was something so special and I still look at it and cherish after ten years of marriage.
2. A personalized photo album filled w/ pictures
I took pictures at the reception, beforehand too if I was in the wedding party, of everything. I took pictures of the food, the cakes, the decorations, the people, and I mean everyone. I took pics of people I didn't even know, just told them I was making something for the bride and groom. I walked around and took pics of people dancing, visiting, eating, drinking. Sometimes the pics were candid and then other times I would tell people to smile and pose. Then afterwards I put it in an album that I had monogrammed w/ the couples names and wedding date. It was awesome and again very special and cherished! I now make it for all close friends or family.
