The purple paper for the boarding pass sleeve we got from Paper-garden.ca, it is Curious Metallics Violette, it is sold at many different companies online I have seen as well. Had I known the quality of the paper I was going to receive I would have ordered our white and teal from this company as well!
The white paper for the boarding passes is from Michaels, it is lighter weight than the purple stuff and it has a small label on the back that says Bazzill Basics Paper, Diamond.
The teal colored small square on the front of the boarding pass is the same kind of paper as the white just a different color.
The pictures don't do any of the paper justice, they are all beautiful deep colors (except the white of course) with a subtle sparkle.
I love the cardstock you used!! What kind is it??
