Flip-book zines are stop-motion on paper, so we borrowed timing lessons from Big Buck Bunny.
Start with plain 80gsm copy paper. It folds cleanly, runs through almost any machine, and costs almost nothing, which matters when you are going to ruin a few sheets learning.
Step by step
Crease every fold twice: once with your fingers to find the line and once with a bone folder or the back of a spoon to set it. A crisp fold is the difference between a zine that lies flat and one that springs open on the table.

The photos are great. Is that the laundromat on Elm?

Do you trade? I have a perzine about bus drivers I think you would like.

Legal size works; just trim a strip off the long edge first.
