Good Morning!

I'm using Word to design a menu in a bar. It's 3 separate 5x7 panels and my menu paper is 8.5 x 14 so my plan is to put two duplicates side by side, and create 3 separate docs.

My first thought was to setup a landscape 8.5x14, make two columns to split it, and then limit margins to 5" high. It hasn't come together just yet, but I feel I might be on the right path. In addition, is there a way to make that happen so everything I input is duplicated on the opposite side? My search for mirroring brought up a different option.

Thanks again for your time and experience.
