Each side is full piece of standard paper 8.5 x 11 oriented as portrait, not landscape. So if you opened it and laid it flat it would actually be 17 x 11. Do not design it that way. Design one separate page for front and a separate page for back.

Hello there, the text can be edited in AI files. So which format do you need if not Illustrator files? Also what info would you suggest for Back design? Thanks.

Hello again. So I've come up with a design and your feedback would be very welcome. If you have any changes and adjustments in mind just let me know, thanks.

Good afternoon. I have lots of great designs to review and I’m traveling until Monday. I will select a design shortly after that.
