I finally have this all put together and ready to mail on Monday (which will be about a month before the wedding). I had finished the luggage tags ages ago but waited on the mailers because I kept redesigning it and adding more info.
For the luggage tags I used clear rigid tags - I wanted something a little more substantial than a typical badge holder yet didn't want the permanence of self laminating. I ordered the tags from the link below and then the straps from Amazon. I printed a few different designs using Microsoft Publisher - one side has a tropical beach picture (just random photos on-line) with wording I borrowed from another BDW bride and the other has one of our logos with the name and address lines. They are standard business card size so I figure people can continue to use them however they please.
