What did you do to make your wedding EXTRA memorable for the guests?

I'm part of a whole group of friends who are getting married within months (in my case within weeks) of each other. So the majority of our guests will be at ALL the weddings............and we all just happened to want basically the same color scheme.

There isn't any viscious fighting between us or anything close to that....but my wedding just happens to be the last of the group and I'd like to do something special.......but within my teensy tiny budget.

Any ideas?

We did a bunch of things but the big winner was the personal notes we wrote to each guest. It wasn't a 'thank you' per say, more of an expression of how much it meant to us to have them there and a special memory (ie I remember sleeping in a tent in your backyard...now I'm all grown up, etc) we shared with each person. It was a lot of work, but probably 75% of our 200 guests told us how touched they were. We wrote on small notecards and bundled them on each table. Here is a pic:
