Getting here, I presume you have printed the zine version of a paper on letter-size paper (Canada and USA) or A4-size paper (everywhere else). I presume you were able to print both sides of a single sheet, or that you can glue together both pages so that the blank sides kiss. The front-to-back rotation should be on the short size of the sheet of paper. The zine is folded in divided in 8 sections.
You now have a M-shaped zine (or W-shaped if you live in the southern hemisphere). You can read it as if turning the pages. Having read the fourth section, keep opening and closing the folds as if they were book pages. Surprising how many words it takes to describe this otherwise very simple book-like motion. One day I'll draw all this and do away with these clumsy verbal instructions.
