A Look at Hedi Kyle’s Diagonal Pocket Folder

This week I thought I would take a short break from a large project I am working on and try out another set of instructions from The Art of the Fold. I picked #23: Diagonal Pocket. (I posted previously on the Franklin Fold.)

I was mostly interested in the interlocking structure at the point, so the following images cover making and locking just that end of the folder.

The image below shows Steps 12, 14, and 15. I skipped step 13 because I learned to do a squash fold differently. You flatten the triangle so that the edge indicated by the pointy finger on the left squashes flat onto the fold below (pointy finger on the right).

You might find it tricky at first but if you plan to fold a bunch of these, it will save time.

It took me a while to ‘see’ what was going on in the next step, but I finally got it. You want the fold indicated by the black pointy finger to open flat (right green pointy finger). You may find this step easier if you score a horizontal line where I have drawn a line in pencil (left green pointy finger). When done correctly the opened fold will match your scored line.

I found it easiest to repeat this step on the left side by undoing the fold on the right to get it out of the way. I refolded the right side after the left side was folded.

I tucked the right hand triangle inside the pocket on the left.

The final step is tucking the triangle below the pencil line indicated by the black pointy finger. You want to fold it under and up. This can be another tricky step, especially if your paper is stiff. I found it helpful to score along the pencil line, even though there is already a fold line.


If you are making this project from The Art of the Fold from paper with a ‘good’ side, start your folding with the ‘good’ side down. The introduction to the Diagonal Pocket mentions sewing simple structures into the folder, but you can also insert an accordion. You will need an accordion with an odd number of pages as the first page is inserted into the open end of the folder.

If you would like to look at another set of instructions for this structure, you will find a full set from 2015 on Encasing Structure.

If you want to enclose a thicker text block/accordion, the structure can be adapted by following the diagram below. The red rectangle shows the height and width of the text block. The full sheet of paper is twice the height of the text block. The black pointy finger indicates where the first fold should be when forming the pocket end. (Everything to the left of that line is the pocket end, and is twice the width of the text block.) The two narrow vertical sections are the thickness of the text block, while the two larger rectangles are again the height and width of the text block.

In other book arts news:

John Neal Books has again updated its list of online calligraphy classes and workshops. You can find the most recent listings here.


And now for something completely different:

As an artist with my email address online in a few places, I occasionally receive spam emails offering to purchase my work. (I get real ones too: the difference is that in real ones the writer mentions works by name and explains where and when they saw the work.)

This week I got a completely new variation.

    Oh! The wretchedness of spam!
    I’m afraid I cannot make a donation, not even a tiny one, but I would like to know more about your paper-weight!


    • Byopia Press says:

      The paperweight is actually a jadeite cicada pendant (too heavy to wear) bought on eBay. From China and “hand-carved” which it may well be given its origin. Based on historic carvings so they used misleading words like “antique” and “historic” in the description. If you look carefully you will find hundreds listed purportedly from different sellers though I suspect it could be just one source! I looked through until I found the cheapest. Also bought a brass cicada which David uses as a brush/pen rest.

        Thank you I did wonder, at first, if it might be Inuit, though I doubt they’d have cicadas! Then I thought Chinese, but probably modern.It is lovely. Peter has a lovely BC jade bear, with a fish in its jaws, but it is not in everyday use as I’d hate to break it!

        That does sound quite precious!

    Love this fold! I have taught it to various groups over the past ten years. Most popular was inserting a signature with a pamphlet stitch on the first fold. That Hedi Kyle – what a clever paper artist!
