I can comment, but I don't see a place to ask a question.
I'd still prefer to try one of the more compact versions rather than US trade this time.
A5 is comparatively compact, and you can get more words per page than Pocketbook, so fewer pages, making the book cheaper to create, and therefore to sell. The example I gave you was based on one of my A5s.
I admit I don't sell a lot of print books, but when Lulu offer free shipping, as they do from time to time, I alert friends to this. Would I be right in thinking that even if the pocket and A5 sizes are only printed in the US that any free shipping offer is still on?
I have no idea to be honest, I don't live in the USA! But my A5s and Pocketbooks (before I dropped that size) are printed in the UK where I live. I think it's just Standard Paperbacks and the Hardbacks that are only printed in the USA.
And yes I am in the UK (my spelling of 'colour' is a dead giveaway!)
What do you class as not a lot of pages?
Page count can be increased, though.
Do you have a Title Page?
That can be followed by a blank.
Do you have a Copyright page?
So can that.
It is also a good idea to have consecutive pages in colouring books blank also.
I would assume page count also needs to be divisible by four.
Watch what option you select in Create, because if you want an ISBN and Distribution, not all options can have them. (The ones with the tick can.)
US Letter Perfect Bound Paperback is a good size, and can have an ISBN, but you will need to get your page count to at least 32.
The paper Lulu's printers use is often thicker and whiter than is found in most mass printed books.
And oh, you can always create more art
