I am doing a cruise wedding in June of 2011. At first I was going to do STDs, but I have told almost everyone on my guest list already. Since I am on a budget, I created newsletters and will be giving those out to the "maybe" people and the "yes" people. I bought really pretty paper to print them on and I went to a craft store and put different stamps on my envelopes. I wanted to do something really pretty like the booklet you showed, but I am just not creative like that. So, my newsletters have an "invitation" feel to them, and they also include everything about the trip. I also have a website. I am notifiying everyone now because I want them to be able to save their money. So far, I have had a positive response.
