Looks great, thanks for sharing the PDF, I know what it was like looking for feedback. It was weird the first PPT didn't work for me but as a 2+ year Mac user I am realizing now there are still some things that wont translate perfectly... oh well!!!!
Sooooo as for my feedback
-LOVE the graphics and things you incorporated for images, the patterns for the "tear offs" are so nice and a great way to add a punch of colour
-The flowers on your first page look awesome
-Love Scriptina (who doesn't)
-the second boarding pass for the RSVP is so creative with the passenger name portion they fill in... wish you were around when I was creating mine!!!!!
-I would reduce the bottom "swirl" or "flourish" on the bottom right hand side of each page where it interjects with the bar code. I think the top looks great and the symmetry would be nice.
- I like the background graphics but consider making them translucent so that your text "pops" more against them. This wont compromise your colours but will enhance the communication of your mesaage
-You all ready mentioned punctuation wasn't perfect on the PDF version so I don't want to rag on it but I would check that out again too if you haven't already!
I hope this was helpful and constructive. I think you did a really amazing job and obviously put a ton of work into them. You will be so pleased when you start hearing feedback from your guests who will truly LOVE them as they likely haven't seen boarding pass invites before!!!
Happy planning and I look forward to many more DIY projects!!!!
