After looking through a bunch of illustration/art/design books, analysing and logging the various layouts I came up with a fair few spreads or pages that I felt were quite effective. Obviously they will need to be edited and adapted to fit on one grid otherwise the flow of the book will be quite strange. But here are the ones that I've pulled out of books that I think work well.
This is the selection I will be using to set my work & my text on. I'm not sure how to choose at the moment. It was suggested that I devise a random process similar to the process I'm using for subject matter to choose to give the book a completely random element. That could work well if I structure the beginning to introduce it properly before giving over my design to chance.
