I created this mock up of my double page spread. The dotted lines represent the centre. On this mock-up I have used more space for images than for the actual text as my two research double page spread shows. I have the mast head at the top so it is nice and easy to see, and I have the text in two different places, so that it is not just one big block of writing, it is seperated out.
If you click on this image, it shows the proper one which isn't as dark and easier to see.
