The 'finished' book, had to be looked over for spelling mistakes, bad grammar (I've adapted the story in parts and edited it to suit a comic book format) and squashed lettering.
I then added white borders around 1/4" to all the white background pages, which was challenging when the pages were 'off-centre' and then reduced the page sizes back down to size.
Following that exercise, I had to go over all the pages where any faint ruling lines appeared after the formatting.
Then, once everything seemed to be done, I printed out my mini-book, a tiny copy of the book itself, so I could be sure the thing worked - which lead me to add more end papers and a new page of drawings.
The result is that the opening page is now correctly facing the reader, and the page count balances. And, you won't believe this, but I just noticed a real problem, that I didn't notice until the thing was in my hands. I've made a screen shot to let you see what it is:
I've got a rogue page, and a double-page at that, this could be hours of work because the double- pages have to be placed properly or they'll be on two sides of the same page. Still, it has to be done. As I said, it isn't over until it's over.
Anyway, although the book is in black and white, and half-tone (shades of gray), I do have a few pages that I coloured - just so I'd know what a colour version would look like.
