Environmental Issues brochure and billboard hoarding

I looked at various leaflet folds and tested them out, whilst doing so I thought of how the leaflet layout would effect how my information would be displayed. Taking note of what folds would improve the layout of my text and images. Below are some folds that I looked at:

I quite liked the roll fold, the traditional tri-fold and I particularly liked the accordion fold.

After mocking up a variety of the leaflets I had found, I decided that I still liked the Accordion fold and wanted to design my leaflet using this style. It has 2 sets of center pages, leaving a generous space for information, facts and images. I liked the sectioning of this layout, the folds section off singular panels, great for uniformed type and great for minimalist front/back pages.
