+ Folio - two pages per side of sheet
+
+ Quarto - four pages per side of sheet
+
+ Octavo - eight pages per side of sheet
+
+ Sextodecimo - sixteen pages per side of sheet
+
+
+
+
+
+ Folding instructions for quarto/octavo
+
+ Folding these two layouts is slightly more complex than the simple single-fold
+ folio. Both of these have been designed so that the first fold is parallel to the
+ short edge of the paper - eg, if you hold the page in portrait orientation, you will
+ be folding the top edge to the bottom. One side of the page will have consecutive
+ numbers across this fold (ie, 3 and 30 on the top row, 2 and 31). Fold inward across
+ this line (so that 3 has been folded to lay against 2, and 30 against 31). The next
+ fold is along the other paper axis (parallel to the original long edge). For quarto,
+ you want to find the side with the numbers closest together, and fold inwards to
+ match them (this will be consecutive on the innermost sheet). For octavo, look at
+ the bottom-most row and find the consecutive pair, then fold inward. Octavo has one
+ last fold, for which you want to find the pair remaning that are closest, and fold
+ them together.
+
+
+ Or, if you want to just memorize the order, once you find the first fold side, the
+ order is:quarto - top to bottom, fold points away from you, left to right, fold points
+ towards you.octavo - top to bottom, fold points away from you, left to right, fold points
+ away from you, top to bottom, fold points towards you.

+
+ Single Sheet Zine - 8 per side (one sided printed page foldup)
+
+
+
+ Instructions
+
+ The classic no-cut, single page zine! Just fold it up right and you've got yourself
+ a mutant non-standard folio making an 8 page little fellow-- all extra pages beyond
+ 8 are discarded. For better folding instructions than I could possibly write, see:
+ https://www.quarantinepubliclibrary.com/tutorial
+
+
+
+
+ Small - 18 per side (3 folio signature per row x 3)
+
+
+
+ Instructions
+
+
+ THIS IS A LANDSCAPE LAYOUT. IT MUST BE PRINTED AND "flipped on the short side"
+ (the non-typical flipping)
+
+
+ Cut out the rows. Fold up the folios like a zig-zag (two per face). Then fold the
+ center of the text (smoosh the two matching page numbers together).
+
+
+ Note that when folding, it's important for the
+ center of the folios to line up . That's what I measure against (less so
+ fretting about folding exactly at the edge). Remember! Printer skew is a real thing!
+
+
+
+
+ Little - 20 per side (3 folio / 3 folio / 4 folio signatures)
+
+
+
+ Instructions
+
+
+
+ Cut along the cut lines. Fold up the 3 folio signatures, then the 4 folio.
+
+
+
+ Tiny - 32 per side (4 folio signature per row x 4)

+
+ THIS IS A LANDSCAPE LAYOUT. IT MUST BE PRINTED AND "flipped on the short side"
+ (the non-typical flipping)
+
+
+
+
+ Cut out the rows. Fold up the folios like a big zig-zag (two per face). Then fold
+ the first 2 folios into a signature and the last 3 folios into a signature. I often
+ cut them apart only when I'm stitching things together.
+
+
+ Note that when folding, it's important for the
+ center of the folios to line up . That's what I measure against (less so
