So, it turns out that creating a re-usable Zine-style layout in LaTeX will be mindnumbingly brutal. Like, I know it can be done, but there is really no way I'm going to do it.

@FinalGirl I wrote a python script that takes a pdf input and produces a booklet/zine imposition output. pdfjam looks cool from the other comment here, similar idea.

My script doesn't scale beyond one signature's worth of pages though, currently (so if I have more pages than I can staple it'll not work).

I use my script to make micro zines (1 piece of paper, 16 tiny "pages").

I'm trying a 16 page A5-sized paper zine right now actually, a booklet basically made of 4 pieces of A4 front and back printed.
A4 paper is cleaner for making zines with the way I do (folding A4 into A5 or smaller sized pages).

@FinalGirl I found my old post about it!
Includes a Github gist from my inspiration source:

@True ash thank you. I was talking about the individual page layout. As in 45° angle tax going across the page pictures splashed down the page little boxes of text different fonts, etc.

I.e. layout to make the pages look like pages in a teen magazine.

@FinalGirl Oooh, good luck! I mostly imitate the effect with wallpaper invocations and a lot of iteration in my drawings to get things lined up as I edit drafts.

Maybe I should look into making my own latex documentclass for once...
I know a lot of people that would enjoy it.
If only we all had more time, argh! I've got too big a TODO list at the moment to devote to yet another project.
