I am surprised I didn't think of this, I usually look for times when
pre-embossing will help. I never really thought of it as a way to make
things faster. I always think of it as a way to make things neater. I
thought it would take too long to line up the ruler, I mean it's a pretty
quick fold anyway, but when I tried it I was surprised how fast it felt.
Thanks for the good idea.

How EXACTLY do you find the top corner. After I pinch the corners, to find
the top corner I have to line both edges up anyway which makes things
slowish. So what's the fast way to align the top corner?

================

One thing I've found (surely others have too but I've never seen it here),
bisector going into the corner with my thumb nail by pressing the paper
between my thumb nail and the pad of my first finger. Then when I get to
corner, using what ever method I'm using to fold the diagonal, the corner
just kind of finds itself (no need to gently fold and roll the crease to
find a good corner).

===============

Folding a diagonal seems like a pretty basic thing. So basic maybe we all
think we know the best way (or at least a good enough way), or think it's
so basic that it doesn't matter (any body can fold it so why talk about
it). To me it is so basic that it warrants a good deal of thought (someone
said something like "if you fully understand the ant you understand the
universe (sorry I can't remember who said it or who told it to me)).
So, I'd like to hear your thoughts. What are you're diagonal secrets?

I just got the Tea-Bag Folding book by Kricskovics Zsuzsanna. The models
are made from the envelopes that tea bags come in. The problem is that they
use envelopes from a specific brand of tea which I have no idea where to
find. The brand of tea is "Pickwick" and I'm wondering if anyone knows
where this can be bought in the USA or from where it can be ordered or
where their internet site is or what their address is or what country /
city they are in.

One bit of info for anyone thinking of getting this book. The models are,
IMHO,  easy and WONDERFUL, but (and it's a big but for most folders) most
or all of the models are unit with NO CONNECTORs (read, you glue the pieces
onto a cardboard backing). I'm thinking it won't be hard to devise
connectors but just thought some of you might like to know that you can't
make the models as they are shown without using ~@#~@#$ (that's *glue* but
I couldn't bring myself to actually type it).

Hmmmm, hard to say.  I'm moving away from the line up the opposite
corners technique and more towards a corner bisector approach.  Line up
the two raw edges that come together and bisect one corner.  Hold the
paper in that alignment and take a few gentle sweeps across the crease.
You're guaranteed to get one pair of edges to line up.  If your paper is
perfectly square everything else will fall into place.  If your paper
isn't square, then you'll have a different error to adjust to than if
you had lined up the opposite corners instead, but it doesn't seem to
matter too much either way.  If you have a seriously non square paper
then you might have enough of a strip to bother trimming off, but I've
never had that happen with prepackaged origami squares.

I've been wanting to tell you that my class folded Nokki and Lekki.  They
had no trouble with it at all, and the little snowlets look really cute.
The kids made real interesting eyes, and the feathers are something to

ordinary origami paper.  Some of them set right off colouring the white

I think this had come up on the list before, though I don't recall
hearing of any source in the USA... BUT, as the author says in the
beginning of the book, even for the tea bag wrappers she does use for a
particular unit/model there are often different ways to cut the square
from the tea bag wrapper, so any kind of patterned paper will make nice
models, its only if you wish to exactly reproduce her designs that you
need the tea mentioned.  I only mention this publicly so that others
thinking about getting this book are not put off by the scarcity of find
the tea/"right paper". ;-)

I might also note that such greats as Valerie Vann, Michael LaFosse, and
others have designed unit origami rings and other modulars which rely on
the adhesive strip on square post-it brand notes to hold the model
together.  Maybe that would work for the models in this book too!
post-it brand notes come in a variety of colors and with a bit of
creative painting, rubber stamping, etc. very cool looking "tea bag
wrapper substitutes" can be made.  It might make a nice art class
project for a school or two too!

I'd love to give this a try but don't really get it. I understand and have
done tessellation's so I get that part of it. I just don't get what you
mean by "fold a grid of square twists". Are you saying crease a 4X4
tic-tac-toe and collapse that into a tessellation (if that's it I'm  more
confused than I thought), or do some (?) precrease pattern that results in
a 4x4 tessellation of squares (that I would understand, but what's the
crease pattern). You said, "In this book, ...all he does is provide rough
sketches of the crease patterns". I'm not sure what you mean by rough, but
I though all you need for tessellation's was a crease pattern (unless there
is more to these than the tessellation's I have folded).

I really love these and would say ThankYou 1000 times (perhaps not in base
10 ;-)) for any further help you can provide.

I'm not sure what the second book is - probably one of Fujimoto's
self-published booklets.  You find these circulating around every once
in a while.

As for the book "Seizo soru origami...", yes, these two "models"
are in it.  I put "models" in quotes because both of these
folds are examples of origami tessellations (or Hira-ori, as
some like to call them).  In this book, Fujimoto has a chapter
on origami tessellations, but all he does is provide rough
sketches of the crease patterns, photos of what it's supposed
pattern" that you get when you hold the finished model
up to a strong light.  (This is what you see in Paul
Jackson's Encyclopedia.)  Thus, while this book has great
collector's value, and is a pivotal book in the history of
geometric origami, it's VERY difficult to learn out of!

The models are simple in concept.  The "90 degree twist origami"
is just square twists tessellated.  That is, fold a grid
of square twists into a single sheet of paper.  Try a 4x4
grid first, and then try an 8x8.

Once you've mastered that, try the same thing with triangle
twists!  This is much harder, but the twists will fit a grid
of equilateral triangles.

I believe the "120 degree twist origami" is made from the same
concept, but with hexagon twists.  But I'd have to look
at that photograph in Paul Jackson's book again
to make sure.

Right now there aren't any good references for learning about
origami tessellations.  Look and see what's available on the web -
several origami web pages have info on these kind of things.

I'm hoping for pointers on Momotani's Ferris Wheel (from Origami Amusement

It indicates that wires are needed between the units that make up the
frame of the piece.  Is glue needed too?  How do I keep the wires in
place?

I broke down and got a translation by one of the students who does tours
for our college, but she's not actually Japanese and she's not a folder so
if anyone can clarify: when it says to use paper that is one half the size
of the sheets for the gondolas, or one and a half times that size for
another unit, does it mean if I use 6 inch paper for the gondolas I use 3
inch for the one type of unit and 9 inch for the other?   The sheets are
all square, so the math and measurement would be pretty frightening
otherwise (yes, yes, not for all of you, just us wimpy humanities types).

Thanks to all of you who recommended the Montroll books for diagrams for
pieces that look like anteaters and lemurs.  They just arrived from OUSA
and I look forward to folding these elusive models, despite being
sidetracked by the challenge of the 3-headed dragon in the back of

I just want to make sure I get this. When you done you will have one
accurate point at one end of the diagonal, also accurate will be the one
edge from that point to the top point - yes? What will be "as it falls"
will be the top point, the point at the other end of the diagonal and the
edge from there to the top point - yes? If this is correct, I'm confused
(so what's new ;-)).  I know you too well to think that you would say
something with out thinking it through, and I have seen your work so I know
you are quite accurate, BUT - how can this be? When I do this the "bad"
diagonal point is too far off.  The problem could be how I did it versus
how you do it, but I did try it and was VERY careful to line up the first
pair of edges (and point) perfectly. For models where points are not real
improtant or for "play" models this would be ok, but to fold a good one of
the many many models that need all good points - humm? I don't get it Doug?

The way I tend to fold tessellations is to start off folding a lot more

to begin with you might as well put in more.
I could also scan some instructions I wrote but haven't typed up, if you

 I do not have any GIF's of folds but I was thinking of something along this
 line.  Does anyone know what 'sirds' are?  They are those images on paper
 that you look at while relaxing your eyes (you do not cross your eyes) and
 a three-dimensional image appears.  I was wondering if anyone made any
 sirds (single-image random dot stereogram) of origami models or folds in
 progress.  I think this would make an excellent teaching tool for some of
 those difficult folds where a person says, "now how is this done" when
 looking at a simple drawing/diagram.  If a fold were shown in 3d and
 in-progress then the folder/student can see the fold actually 'happening'
 before his/her very own eyes!  Also, there is a rarely done effect with a
 computer which I don't know the name of.  It involves showing a succession
 of sirds like a 3d movie.  Each sirds image is slightly different than the
 next image and the 3d objects actually move around in space.  Imagine the
 teaching value if a sirds movie were to show the folding of a particularly
 difficult step.  Sirds are very easy to make and there are many
 freeware/shareware programs available to make them on almost any computer.
 I am curious if anyone is up to making a few and posting them as gifs in
 the origami binaries pictures newsgroup.  :-)

By guaranteeing that one end of the diagonal crease is exact, you force
any inexactness to the other end of the diagonal.  If the sheet you are
using is really square, you're golden!  If the sheet you are using isn't
square, the inexactness will show up in different ways.  For example, if
you really have a rectangle instead of a square, when you fold the
diagonal this way you'll get a small strip of paper where the opposite
two raw edges should have lined up.  If you're corners aren't 90
degrees, you'll see other effects.  In the rectangle case (which is the
most common non-square paper I've run across), the strip is
often not big enough to bother trimming off, unless for some reason I'm
going to fold a display quality model from kami.

Aha!  I suppose my answer is a bit flippant, but it is still my answer:
why would you want to fold a "good one" from paper that wasn't square to
start with?!  If the paper is really square, this method is really
accurate. ;-)

I ended up choosing this method because when I was testing out the
squarenesss templates I'd bought, the squares I cut seemed to be
slightly off, so I thought the template was off (even though I had
measured it five ways to Sunday).  What I discovered was that using the
"pin opposite corners together" method was generating the inaccuracy
that I was blaming on the template.

I think the former is what Tom's talking about.  Once you can do a single
twist, you can see how you end up with a little twisted polygon with
pleated radiating away from it.  You can see how these pleats could
be the radiating-pleats of -other- twists elswhere on the paper if
you were careful about how you laid it out [and remembered that
twists connected by a pleat have to twist in -opposite- directions].

the easiest thing to try is to do just-two square twists on a single
sheet: the two squares wouild end up as diamonds along a central pleat
with a left-right pleat going from each [sort of looking like a "record
mark" [for old IBM folk..:o)] or a double-dagger footnote mark].  Then you
can try 4x4 or 8x8.

Once you get the idea [how you fold the pleat along the edge of a polygon
to get it to 'twist' as you close the pleat], you can then do very
complicated tesselations if you lay it out and figure out where the folds
have to go.

I have one of those books and believe me, it is a rough sketch and tough
sledding.  It is hard to figure out what the folds are, which are
mountains and which valleys, and how you're supposed to actually -fold- it
when you're done [and that coupled with at-best sketchy views of what
it'll look like when it's done makes it harder than I can deal with.  Then
you get something like after a diagram of a crease-pattern, there's
a little diagram with some creases and arrows on it and a paragraph of
japanese next to it.  What is it?  Hints for folding? An alternate way to
make the creases?  A quick outline of a change that'll make a different
pattern [that is, the text could read "but if you want the twists to
overlap cleany, you need to move fold A so that it is outside this
corner... or some such]?  Makes for a nice enigma.  Tom said that he had
succeeded in puzzling most of the way [all of the way??] through one or
more of those books.  I"ve made it about 1/4 of the way through the one I
have and I"m completely lost...:o)

Subject: Re: The Twist

I recently received in the mail Chris Palmer's video called, "Hira Ori"
which is wonderful!!!  The tape is organized into three sections.The first
section is boxes which contains a square twist.  The second section
is origami flowers and there is also a third section on
tesselations that I haven't "done" yet.  I've watched it once, but haven't
had the time to sit down with paper and VCR remote to stop, rewind, etc
and actually complete the tesselations.  The video is very carefully done
and for the most part contains easy reference marks that allow the viewer
to do what Chris does in the video.  I can't remember if there is a
hexagonal twist in the video, but there may be.  There is a pentagonal
"twist" in the flower tower model.  I got it from Origamido - Michael
LaFosse's "store" (?) in Massahusetts.  You can see his web page at

by Toby Schwartz and Dor Jeong in fashioning the 1000 plus cranes into a
lovely rainbow creation.They look really lovely hanging between Sue's living

All people can't see sirds/stereograms however hard they try. Nice idea
anyway. Sirds can also be animated, but as they are basically noise
(very special noise, but anyway) the resulting anims are huge.

Michael is becoming so prolific that soon we'll have an entire collection of
just his books :-)
His latest accomplishment is entitled:  Paper Art: The Art of Sculpting with
Paper.

This book, although not solely devoted to Origami, is one of the most
beautiful books we've seen. It is hardback and includes many of the world's
best paper artists working in a variety of mediums. Origami artists include
Chris Palmer, Tomoko Fuse, Akira Yoshizawa, Eric Joisel, Herman van
Goubergen, David Brill, Paul Jackson, Robert Lang. Hopefully I didn't leave
out anyone :-)    Although not origami, there is a beautiful pulp paper dove
by Richard Alexander, too - a very nice surprise.

This book is incredible! Paper Art celebrates the beauty, versatility, and
wonder of paper sculpture, paper folding, paper mache, and paper as a medium
for art. In these pages, you will visit paper artists at work in their own
studios, and will learn how to apply their special techniques to your own
art work. Watch as he work of gifted paper-artists unfolds step-by-step in
more than a dozen projects. Gather inspiration from each artist's individual
approach to shaping plain pieces of paper into fascinating, dimensional
works of art. Material lists, sketches, and step-by-step photographs
document a range of challenging techniques. Full-color gallery sections of
commercial and fine art showcase the amazing diversity of paper. Learn from
an international roster of artists from England, France, Canada, Japan, and
the United States.

It's the featured book on the Origami Book page, but you could also easily
locate it using the search engine.

Subject: "least favorite":  hard to do vs. drudgery

For me, "least favorite" means "drudgery."   I am "capable" of folding good
spirals if only I had the patience (thus the stylus might be a good
solution).  But I think for some "least favorite" does mean "hard to do."   A
fold can be annoying for lots of reasons, e.g. there's a failed parabola in my
trash right now.  (Gee, I'm still thinking about that parabola and how it went
wrong.)

The only problem was that some places poked a hole in each lid

True. I've got several of them. The problem is that most are from rather
obscure Japanese publishers, and were published some years ago, so they are
possibly out of print.  There is little to regret, though: most of these
books are for children, and full of the usual boring simple stuff..... ;-)

There is a store in New York City called Fishes Eddy.  I believe it is on
 Broadway at 77th street, not too far from the
American Museum of Natural History.  They have a lot of restaurant overrun
 plates, glasses, etc.  Also the kind of sugar
containers, packet holders, cream dispensers and the like that you might find at
 your local diner.  They have carried large
pickling jars an pasta holders that would do fine for holding cranes.

I also recently picked up a couple of spaghetti noodle jars from Ikea (the one
 in NJ by Newark Airport).  I display a
collection of seashells in them now, but they could nicely hold cranes.

My husband suggested the Flemington Glass factory in Flemington, NJ.  They have
 an outlet at the factory that sells imperfects
and seconds, so you might get a bubble in the glass, but the price is right.

Hoo boy!  This has been discussed a lot on origami-l in the
past.  A number of people have tried to come up with a way
to capture paperfolding in a symbolic language, and no one
has succeeded.  The problem is with all the different
origami maneuvers (twists, open sinks, closed sinks, half-closed
unsinks, bite folds, etc.) there just seems to be an unending supply
of origami moves that can't be classified by previously known
moves.  This makes such a symbolic language very sneaky.
I for one am a skeptic. Making a program that will be able
to simulate *any* and all types of folding may not be
possible, partly because...

several people, including a number of research teams in Japan,
have and/or are trying to do this.  The only success I've seen
has been with programs that can handle only simple
folds.  Even the "Mathematica demos" that someone else hinted
at can only do things up to the flapping bird.  I haven't heard of any that can
 handle sinks.

Anyone who is serious about this "virtual origami" problem really needs
to read up on the origami-math literature out there.  I'm
talking about the articles by Toshikazu Kawasaki,
Jacques Justin, Robert Lang, and especially the
article by Marshall Bern and Barry Hayes called "The complexity
of flat origami," where they prove that the basic problem
of determineing whether or not a collection of crease
lines can be folded into something flat is NP-complete.
And if that basic problem is NP-complete, then the bigger
problem of virtual origami is very likely to be very thorny
indeed.  All of these articles are referenced in the
origami-math bibliography on my web page:
http://www.math.uri.edu/~hull/OrigamiMath.html

And the recently released book "Origami Science and Art:
Proceedings of the 2nd International Meeting of Origami
Science and Scientific Origami" contains many of the
most current articles on mathematical modeling of origami.
See my web page for info on how to get a copy.

I do hope that helps.  Good luck!

This book is long out of print. What do the used book gurus have to say?

Hi !

I joined this list just before the break in listserver.
My name in Janne Mantyla, and I study CS in Helsinki
University of technology in Finland. The topic of this
mail is actually why I joined this list...

I started by reading a book on origami about 15 years ago,
was under 10 years old by then... and here we are now :-)

Sidrs (for Single Image Ramdon Dot Stereograms) are not a good
technology (IMHO) for showing anything that you want to see
clearly. You get your eyes sore and the resolution is not that
good. Animated gifs are good because everybody has a browser that
can view them, just that a good 3D videoclip takes quite alot
of space. I'm thinking of making a 3D folding instruction with
OpenGL. If I construct a mathematical model of a paper and compute
it in real time, the resoluton will be terrible, so I think that
the computing has to be made in forehand. It seems to be quite
complicated. The animation could of cource be transformed to, say
.AVI or .MPEG format, but then it wouldn't be anymore interactive,
you could not turn the object around. So the options seem to
be precomputed and displayed with OpenGL or a movie in some
standard format.

Some questions:
1) Does anyone now of a (BNF) language that
   could specify exactly any folding ?
   I would like to start defining such a language,
   that "anyone" could write to define a folding.
   That way we could make a library of folds,
   that would be machine/architecture/program independent.
   http://www.origami.net/homes/jwu/Info/Oil/oil.html
   was interesting, but it is 23 years old and was
   not designed for computers.
2) Does anyone know of any project that had tryed
   to model paper and perhaps interactive folding
   in 3D ? I'd like to have pointers...

I've got a very preliminary proto, and the problems are
just coming visible... wish me luck 8-)
