Nice! I haven't spent much time using twine yet but i'm excited to try it out properly! Hope you can get round to them, have you got any set ideas yet? ^^
Forgive my awful mspaint template but a one-page zine will look like this when it's unfolded! The red line is the line you cut to be able to fold :) I tend to make mine on paper and then scan them in so the print layout is their default and then i crop the images and put them into a pdf for the web version!
