@Sandy, I've just posted my boarding pass save-the-dates! It was a lot of work, literally an entire day (9am - 8pm) of folding, cutting gluing, embossing....but totally worth it in the end ;-) I used the same template as AnaS although I couldn't for the life of me make a proper pocket shown in her template so I started experimenting and ended up making one of my own.
Here's the link: http://www.ayleebits...-save-the-date/
For the pocket, I embossed the leaf by purchasing a leaf stamp, clear glue "ink" pad, white embossing powder and I borrowed my friends heat gun (I helped her with her wedding invites and learned about embossing then). It took a few tries to get the hang of it, but after that it was smooth sailing.
The inside pocket is open on the left side with the rounded corner. Here I used a rounded corner cutter which probably has a special name that I'm not sure of. The bottom is closed.
And here's the whole package
