I also make the pdf files for DIY moms. Here's a DIY tip for you, if you decide to make pockets to go with the tickets... I had the TOUGHEST time making this heavy cardstock stick with just my ATG tape (which is excellent in most cases). I handmake the pockets myself. But because this paper is heavy, it tends to pull away. SOooooo, I went and used my trusty Scotch double sided tape, and that seemed to solve the sticky problem.
These tickets are also cute by themselves, if you stick them in a colored envelope. A great place to get many colors is http://www.paper-source.com/.
A Shop Announcement: I am retiring this item from my shop. But I will continue listing it as a "PRINT AT HOME" option for $10 so anyone can print these from their own printers. I will also include a template for the pocket. I would suggest using a medium weight cardstock for pockets.
