Thanks to everyone on this site, I got so much pointers for my boarding pass save the dates.
First, I used http://www.ayleebits.com/templates.htm for the boarding pass templates. Then I bought 1 pack of Aspire Petallics Snow Willow card stock and 1 pack of Stardream Ruby card stock. The Ruby cardstock was used for the boarding pass sleeves. I wouldnt recommend using the Ruby card stock for the sleeves because they were a little too thick. I also got silver metallic envelopes. I bought everything from www.lcipaper.com
Here are some pictures of my drafts.
There's holes in them because I was trying to figure out where to position the brads.
I embossed the sleeves and wrapped raffia ribbon around them. You cant really tell but the silver metallic envelope is in the back.
I hope this helps. Let me know if you have any questions.
