Threads, a Zhen Xian Bao, Paula B Krieg
Threads, a Zhen Xian Bao, Paula B Krieg

I just sent this piece out to be in a show in Massachusetts. Included with the piece is an invitation for the book to be handled and for the viewers to take a piece of it with them.  As you might suspect, there’s a bit of a condition.

I’ve been making models of this folder of expandable boxes, known as Zhen Xian Bao, for quite some time. I’ve been so busy deciphering the structure and creating designs for the papers that I make them out of that I haven’t thought too much about what to put into these boxes, which. traditionally, were used to store thread.

Here’s the chronology of thought then. First structure, then embellishment, now content. Finally I’m ready to think about content, now that I am satisfied with some of the solutions to my first and second considerations.

Here’s what I’ve put in the boxes:

There’s about 64 paper tiles stored in the various boxes of this structure. Each tile is threaded with a loop. The back of each tile has words or phrases that I repeat to myself, the threads of thought that help me get through my days.

I had wondered if I would be able to come up with 64 things that I tell myself, so I asked my a couple of friends for some of their thought threads. I included some from Jocelyn, especially liked “Bring a book,” and Susan’s “Mend a thing.”

Funny thing, though, after I got started, it was easy to come up with scores of things I tell myself.  So many thoughts woven into a day.

Now, here’s a box of blank tiles that I’ve sent along with my work. There’s three of these boxes. They are meant to sit alongside my Zhen Xian Bao. There is also a pencil in each box. I’ve sent word that I am inviting viewers to add one of their thoughts to one of my boxes. Then, after they’ve made their contribution, they are invited to take one of my thoughts with them.


I don’t know how this will work out. As there are tiles in each one of these 13 expandable boxes, I am hoping/anticipating that my Threads book will return with wear and tear showing. I will consider evidence of handling as the finishing touches.


Now it’s out of in the world, out of my hands!

Chinese Thread Book To Go

This past winter I submitted a proposal to the National Museum of Mathematics to present a family workshop at their paper folding MOVES conference this summer. Much to my surprise (and non conveyable delight) they accepted my proposal for hands-on workshop in which people would make a Zhen Xian Bao -Chinese Thread Book- made of three expandable origami boxes, housed in a cover with a ribbon closure.

Much more to my surprise I realized that my workshop time was strictly only 25 minutes.

Finally even much much more to my surprise, the workshop worked out great. Here’s why:

  • I created a highly simplified variation of the thread book
  • I made packets so no time was lost handing out materials
  • I included written instructions so people could work independently
  • I made designs on the paper that would help guide the folding
  • I made a video of how to finish at home
  • I relaxed and had fun

Now here’s the shocking part. Everyone finished their project.

Full disclosure, since this was the very last workshop of the day, we were able to run a little over time. But just a little.

Making a video of how to make this structure was key for me to create an good event. When I realized that I could give people a link that they could reference at home everything seemed doable, and we had a great time with no pressure!

This was a family workshop, though most people were solo. I did have three kids in the room, and they were all very good about helping their parents.

So, yes a good time was had by all. As usual, I completely overprepared (something I do when I am nervous) (which, actually, is always) and the good new is I actually HAVE LEFTOVER PACKETS! that already has a video that goes along with them. I AM SELLING THESE ON ETSY.

The packets includes the paper for the boxes, directions, a cover piece that is prepared with slits for the ribbon and double-sided adhesive tape already applies, ribbon, and a link to the video (which will also appear on my Etsy site). Also I’ll be giving you a few paper strips which you can use to decorate the cover.

The finished, closed thread book is about the size of a large cell phone: 6″x 3″.

Here’s the video that shows you how to make this structure:

Here’s the link to buy the kit on Etsy:

It’s $15, which includes shipping in USA.

Addendum: The kits sold like hot cakes…they are now no longer available. Grateful to all who bought them!

Indigo and Suede, with a Pinwheel Twist Box


This continues my posts about assembling different structures based on the Chinese Thread Book, using different papers. I had thought I was going to be doing the same thing over and over again, with no variations other than using papers with different colors and patterns, but it hasn’t worked out that way.wp-1484682930002.jpg

Here’s where I started using the Stardream Metallic for the cover of the pamphlet on the left. More and more I’m liking how the Stardream paper matches the Chiyogami printed papers.  Notice the style of the little box inside of the pamphlet. After trying out many variations I absolutely loved this little twist box with the pinwheel top.

I think it’s something about the pattern of the Chiyogami paper that made other style box I’ve been making look, well, not so good. Am so pleased to have stumbled upon this way of making the twist box.


Here’s the pinwheel-top box, twisted open.


The second layer rectangular tray is made from a soft handmade paper from India. Underneath the tray is a sleeve made of Stardream paper, which matches the pamphlet.


Big box layer is another handmade paper, but not sure where it was made. I have a stash of this from a place that Elisa Campbell wrote about, Creative Papers, which, sadly, is no longer is business.


The biggest surprise for me was the choice I ended making for the cover of this Thread Book. I tried matching the book with other Chirogami papers, with handmade papers from Dieu Donne and elsewhere. I tried my (faux!) elephant hide paper, and tried matching it with all sorts of cloth.  Then I tried it out with this piece of suede, and it just snapped together. I never thought I use this suede for anything, but it seemed perfect for this project.

I just love how I get to use all these odds and ends of materials!

What’s different, besides the suede, about this particular piece is that it doesn’t suggest a use to me. The first one of this group that I wrote about seems like a valentine waiting to happen, the one after that feels like a gardener’s journal, and the next one I will be writing about feels like a holiday journal. But this one isn’t telling me what it needs to be. Hope someone else can figure it out.

I can’t believe my good luck.

I’ve been reading about the Chinese Thread Book, devouring anything in print that I could find about it, scouring the internet then just thinking about and trying to make sense of this structure. It didn’t even occur to me that I might actually get my hands on an authentic Zhen Xian Bao.

This is how it happened. I wanted to share what I’ve been studying with book artist Ed Hutchins. When he told me that he wasn’t familiar with what I was talking about I drove to his house and dropped off Ruth Smith’s book on the subject. then received this mysterious message a few days later. Ed wrote: ” LOVED THE BOOK. I devoured it cover to cover. I’m going to try to find my zhen xian bao before you get back. keep your fingers crossed…” then a day or two later “You won’t believe this: I found the sewing kit book–AND you are going to love it!”

Turns out that even though Ed had no idea of what I was talking about, once he saw the Ruth Smith book those memory gears kicked in, and he suspected that something he had in storage, might be of interest to me. Turns out he had, many years ago, bought this item on Ebay, without knowing what it was. When he asked the seller about it, well, the seller didn’t know anything much about it either. Ed suspects that this thread book was part of an estate that was being sold off.

Here’s a variation of boxes on the top layer that I hadn’t seen in all of my perusing: this Zhen Xian Bao features both twist box, and a masu-type box on the top layer, in an alternating pattern.


Looking under the flap of the square boxes with the star on top readily reveals that this box is an embellished masu box.

There are a few things about this masu box that I’ve deemed particularly noteworthy. The first is that the green and red backgrounds of the star shapes are not hand colored, rather, these are colored papers that are adhered to the masu-box paper. The star motif is also decorated with collaged bits of colored papers. The other detail that I thought was interesting is that the masu boxes were made from a lighter weight paper than all the rest of the boxes in this thread book.

Okay, so there’s 16 square boxes, each two of which reveal a box underneath, so, between just the first and second layers there’s 24 boxes.

There’s some precise folding going on with these rectangular trays, but it’s also clear that it’s not what we think of as origami. Its been my impression that the rectangular trays traditionally are more like simple folded templates, but I will continue to make mine with origami methods for the reasons I’ve discussed in earlier posts. The decision mostly has to do with the paper. Oh, and it’s the paper in this book that makes it most convincing to me that this Zhen Xian Bao was made in China. The paper is thin, strong, and has an uneven texture. It’s certainly handmade paper, and it’s not like paper I’ve seen. Actually, this paper’s closest counterpart in my paper stash is the common grocery bag (though I am sure that this similarity is purely cosmetic!).

Next layer down! Here, each set of four top boxes pull away from each other. Now the count is up to 28 boxes.

Please excuse the purple straw holding the next layer open. Now we’re up to 30 boxes. If you are confused by the count, remember that each set of boxes has a symmetrically placed counterpart, so this open box on the right side is mirrored, but currently hidden, on the left.

Finally, here’s the Big Box layer. There are some major tears in the part of this box that articulate the spine. With the big box, there;s a total of 31 individual compartments in this book.

A secret is revealed on the big box layer that I loved seeing…. one thing that bothered me about this structure was the cover. Although there are no rock-solid rules for the cover of the Chinese Thread Book, I found the cover of this one to be somewhat out of place. But at the edges of the material that covers the big box there’s a hint of something different.


Look, at the head of the box there’s an indigo pattern on material that is underneath the red cover paper.

img_0535There it is again, at the tail edge of the box. The red cover was somehow added on, over the original indigo cover, which is a color that makes more sense for this book. Maybe the original cover was damaged and a seller thought to recover the book to make it more sale-able?

I kind of plan on kind of replicating this book using my own methods. Using the measurement methods I’ve been writing about, the only measurement I will need to replicate this book is the diagonal measurement of the square that is made with the 2 x 2 square of the top-tier of boxes.

That’s it. Now I better get this book of boxes back to Ed before I get too used to having it here.


Here’s a map of China from Ruth Smith‘s book  Zhen Xian Bao: a Little Known Chinese Folk Art. I am impressed by how few places these zhen xian bao have been found.
