This is a live workshop, but it will be recorded and available for the registrants to view until July 5, 2022.

This workshop covers the folding of three unusual and non-rectangular accordions: a pentagonal book that can zig-zag or unfold, an octagonal accordion, and a circular/toroidal accordion.

We’ll concentrate on accurate folding and go over some of the basic geometry to understand how these forms work. Covers and wrapper options will also be addressed.

Our focus will be on making models that participants can use as references after the workshop. These forms rely on the folding rather than the hinging of paper. No advanced math is required, but a drawing compass is. Participants will need to print out (or otherwise make) a template sent prior to class. 

Note: Stephanie has taught this workshop for other organizations under the title More Unusual Accordions.

Tools required

Sharp pencil, mechanical best

Drawing compass

X-acto knife and sharp blade.

Cutting mat


Metal ruler

Bonefolder (helpful if the tip is narrow) or something else to score with like a (short) knitting needle

45-degree right triangle, metal best so you can cut against, but plastic is fine.

30-60-90 triangle (optional)


Glue stick

Scrap paper for gluing

8.5 x 11 copy paper for notes, tests, and drawing

1-2 sheets of card stock and any kind of printer to print out template which will be sent ahead of class.


Structure A: Pentagonal

(1) sheets 1" x 16" paper strip.

The grain goes parallel to the 1" dimension, so it folds with ease if folding over to have the short sides meet. You can use anything that folds well and isn't too thick. Sketch paper or 70-80 lb. text weight paper best. Not card/cover weight.

(6-7) pentagonal pieces printed out from template sent, and cut out of any weight card stock

Structure B: Circular/Toroidal

(1) sheet 9" x 9" paper is best, but 8.5" x 8.5" is okay.

Grain can go either way, heavy text weight (like sketch drawing paper) or light cardstock or cover weight paper.

(1) sheet of paper same size for a template, can be the same paper or, if need be, copy paper is okay.

Structure C: Octagonal

(1) sheets 2" x 16” strip.

The grain goes parallel to the 2” dimension, so it folds with ease if folding over to have the short sides meet. You can use anything that folds well and isn't too thick. Sketch paper or 70-80 lb. text weight paper, or 80 lb. cover weight that folds well would work.

For cover or wrapper options, if there is time:

Structure B: Wrapper

(1) sheet 8.5 x 11” card stock or cover weight paper (or can be bigger)

Structure C: Covers

(2) sheets 4 x 4” (or bigger) card stock, cover weight paper or mat board scrap


(1) sheet 8.5 x 11 heavy text weight or light card stock
