Hey, I agree, that was fun to learn. Do you have to say..."of opposing
edges" if you're "mid" and "parallel"?

  Yes, kinda like that. First the hull is sent through the neck of the bottle.
     Then
the rigging is sent through and glued to the hull. All of the rigging is hinged
     and
tied to threads, then the threads are pulled in the proper order (sometimes 50

I have to disagree here; the creases are the part under most stress and
therefore most likely to split when wet/moist. I try *not* to dampen the
creases! However, there is no best method - get some water, lots of
differnet papers and experiment! Start with simple designs at first
though, or it will end in tears or tears....

Subject: Re: correct math term

I would like to add my fiftieth of a buck, if I may.

The term "perpendicular bisector of an edge" is fine for the crease
produced by the book fold, but does not really convey what was done to
produce it (not in the sense the term "book fold" does, anyway). For this
reason I prefer "mid-parallel of opposing edges" of the folding square.

In case some of you are interested, you can check out my article on things
like this in Mathematics Magazine, Dec. 1995. One of the basic folds
"allowed" in the definition of elementary geometric procedures of origami
as defined there is uniquely folding a line onto a parallel line, yielding
the "mid-parallel" of these two lines, i.e. the line parallel to both and
equi-distant from them, as the resulting crease.

If we really want to get mathematical in the nomenclature, what we are
doing here is producing the locus of all points equidistant from the two
parallel edges of the square we are folding onto each other.

By the way, this stuff is fun (just in case you hadnt noticed)! Dont let
yourself get scared by the attempted precision of the terminology; that is
actually one of the fascinating aspects of the math, if you allow yourself
to get sucked in to it.

Subject: Re: Folding paper in fifths

In general, it takes a minimum of four folds to divide a square (in
one direction) into 1/(1 + n) ths.

1) Fold the diagonal (from the lower-left corner to the upper-right corner).
If you think of the square as the upper-right quadrant of a standard
Cartesian coordinate system, this gives a line whose equation is
        y = x

2) Fold the horizontal line 1/n th of the way up from the bottom of the paper.
Better yet, pinch the left edge of the paper at this point.  If you want
fifths,
then this is 1/4 th of the way up from the bottom.  If you want sevenths,
then this is 1/6 th of the way up--you can find 1/3 rd of the way up first
(following this four-step process), divide in half, and then do steps 3 and 4
again to get sevenths.

3) Fold the straight line from the lower-right corner to the pinch made in
step 2 (or if you folded, instead of pinching, fold from the lower-right
corner to the intersection of the left edge and the fold made in step 2).
The equation of this line is
        y = 1/n - x/n
You needn't fold the entire line; what you need is a sharp crease (pinch)
where this intersects the crease from step 2.

4) Fold a vertical line through the intersection of the folds made in step 1
and in step 3.  Setting the two equations equal and simplifying, we get
        x = 1/(n + 1)
so that you have folded, from left to right, into n+1 ths.

One more thought--as a crossword puzzle afficianado, crossword
constructors often speak of crossword symmetry.  One type of symmetry is
"left-right symmetry" -- so perhaps a less mathematically complex but
still precise terminology would be something like:  fold along the
center line of left-right symmetry.

Of course, this could be ambiguous if the folder had the paper oriented

In math we do speak of vertical and horizontal symmetry.
Diagonal symmetry can be considered using the line y=x or y= -x as your line
of reflection.

Well, that's easy if you start from a square. Let me try describing it
with a simple diagram. Let's label the square so:
A    B
+----+
|    |
+----+  (If that does not look like a square blame my editor)
C    D

First, divide edge AB in 4 (easy :) ). Fold corner C to the division
nearest to A (that is, 1/4 the way A to B). The edge CD will intersect
edge BD at a 2:3 ratio; therefore, the length from B to the intersection
will be 2/5, the remaining 3/5. A simple book-fold from B to this point
and you have 1/5 of BD.

Someone (sorry, forgot the name) published a nice collection of n-division
folds for the square (n from 2 up to something like 17) in an OUSA annual
---91, I think. Not all of the methods are rigorously precise, but they're
ok for practical purposes, and a very useful resource.

I still would like a way to divide _angles_, besides lengths. Robert Lang

Well, let's assume we're talking about Crawford's ship (the only one with which
I'm intimately familiar).  The two main sails will push astern relatively
easily, and the jib will fold over the side.  The model could be folded and
pushed into a bottle, then the sails could be raised inside the bottle.  I
think this is the way most ship-in-bottle builders do it.

Most of my favorite models are three-dimensional.

But sometimes I want to include a little model along with a card or letter
that I am going to mail.  I usually use the bow-tie or shirt/pants if I'm
sending a gift of money.  But I can't think of a really good model to use
when sending money isn't appropriate (or I'm broke).

I'm looking for suggestions for models with a high WOW! factor that can
easily fit in a standard letter envelope.   What are your favorites?

I have to disagree with Nick.... The creases are where the paper fibers break
when folded, and that is precisely the area you want to have damp so that the
paper will bend instead.  The drawback to wetting the paper after the model is
folded is that all the creases have already broken the fibers and wetting them
won't fix that, won't make the creases softer.

But I can agree that experimentation is best!

This method does require the use of one tool, a piece of lined paper (the
up side of this method is that it does not put any creases in the paper, it
just shows you where the edge points are). To give credit, Doug Philips
showed me this.

Put a piece of lined paper in front of you with the lines vertically
oriented.

Pick any vertical line which is kind of far to the left of the paper and
number it 0 (zero).

Number all vertical lines (i.e., 0 1 2 3 4 5 6 7), starting with the 0
line, towards the right edge of the paper.

Now place the paper to be divided (called THE Paper from now on) on top of
the lined paper with the edge to be divided oriented towards the top.

Place the upper left corner of THE Paper on line 0.

To divide the edge into fifths place the upper right corner on the vertical
line numbered 5 at the top (you may need to move the corners of THE Paper
so that the upper left corner is near the bottom of the lined paper and the
upper right corner is nearer the top of the lined paper). Mark on THE Paper
where its upper edge intersects the vertical lines #'ed  1 - 4 and you are
done.  [Just to be clear there is no folding involved you are just sliding
THE Paper on top of the lined paper].

That's it. Again, thanks Doug,
Jeff Kerwood

Have you tried squashing them?  A local folder, John Morin, (also author of the
book in the newly released The Ultimate Origami Kit, plug, plug) and I once did
a bunch of models that had to be flat.  I folded a hummingbird and he folded
the traditional lily, but then flattened it.  It looked quite cool (though it
will be thick).

Rohm's Turkey (in The Best of Origami by Randlett) can be easily folded flat
too.

There are a number of unit origami "rings" and such that you could do,
depending on what size paper you are starting from.  Maybe even a tiny Fuse
quilt or two.  Both of those can boost their "WOW" factor with tres cool paper.

At the holiday times, you can use one of several Father Christmas/Santa models
(Sorry, I don't have a favorite in this category), and then of course there is
always Joseph's Snowflake folded from wax paper, or Lewis Simon's Snow Crystal.

Herman van Gubergen has a envelope with wings (I think it is called Air Mail)
that is cool too, and if you fold it from 6" paper, Joseph Wu's When Pigs Grow
Wings and Fly would work (I'd call that 2.5D, since it will be a bit thick
too).

My favorite (flat) cat model would be Rohm's Halloween Cat, also from The Best
of Origami by Randlett), but actually, Toshie Takahama's Cat (in many places,
including Jackson's Classic Origami) is a very close 2nd.

There are lots of flat modular stars that are nice for mailing.
Some sources include:

_Origami: Plain and Simple_ (Hull & Neale)
_Russian Origami_ (Hull & Afonkin)
Beynon's BOS booklets 31 (More 'Igami) and 37 (Jef Ori 3)
   (Beynon's BOS booklets 27, 38, & 44 may also contain stars)
   (I have no idea whether these BOS books are still in print.

Re: Rick Bissell's query:

My favorite flat model with a high WOW! factor is Fuse's nautilus shell
from her book, Spirals. It can be made thinner by lopping off the outside
triangles of the kite fold at the beginning.

Another beautiful flat model, but with a definite wrong side, is the
sailboat in Yoshizawa's Origami Living Nature.

I fold both of these models for the outside of notecards. I also use the
traditional kimono and the Swift Ring by Jose Krooshoop, which appeared
in The Paper, Fall 1995. As Doug Philips mentioned, any modular ring
should work well.

I'd also suggest looking at Francis Ow's Origami Hearts. In it, are some
nice bookmarks, and most of the models are flat, but I suppose you could
not send hearts indiscriminately.

Just to note that I did not invent or rediscover this method, I think I learned
it from this list too.

Just an additional note, you don't even need "lined" paper, since any set of
equally spaced parallel lines will work, if you have an unlined piece of paper
that is big enough, just divide with book/cupboard/etc. folds into 1/4ths, or
1/8ths or however many you need in order to get enough lines for the
technique.  You don't even need a pen or pencil, because you can fold the paper
right as it is lying on top of the grid!

Here are some suggestions (and favorites!)...

Alex Bateman's Square Dance
http://www.sanger.ac.uk/~agb/Origami/origami.html
This is a cool looking tessellation fold that I really like. Most
tessellation folds elicit wows from me. The other tessellations on
Alex's page are also 'wowable'.

Peter Engle's Eight Pointed Star
It is published in _Origami_from_Angelfish_to_Zen_.
This model is flat and handsome.

Sort of along the same lines is the Octagonal Star unit by Toko Fuse.
(It's in _Unit_Origami_.) The unit looks pretty cool by itself. Also,
this would be a perfect candidate for Doug's suggestion of a tiny quilt.

J.C. Nolan's Braided Paper
Although not completely flat (the center of the model has some
thickness), it certainly gets a wow from me.

J.C. Nolan's Andrea's Rose
The more levels you fold the more impressive it becomes.

Diagrams for both of these can be obtained at Alex Barber's site...
http://www.the-village.com/origami/index.html

A model that I found on the web recently is Indicador de Pagina
(Bookmark) by Ricardo Ros Casanova. Perhaps it doesn't have a high wow
factor but is is very functional (and flat). Adding to its charm is the
silhouette of the traditional pajarita on the finished model. Here is a
link to the page the diagram is on...
http://www.geocities.com/Paris/LeftBank/4091/desa06.html
As Ariel mentioned this is an interesting site definitely worth a look.

Here's what Sundara Row has to say on the matter:

"15. Now fold again, as in Fig. 6, laying one side of the square
on its opposite side. We get a crease which passes through the
center of the square. It is at right angles to the other sides
and (1) bisects them; (2) it is also parallel to the first two sides;
(3) it is itself bisected at the center*; (4) it divides the square
into two congruent rectangles, which are therefore, each half
of it; (5) each of these rectangles is equal to one of the triangles
into which either diagonal divides the square." p. 6

"22. Now take this square piece of paper (Fig. 9), and fold it
double, laying two opposite edges one upon the other. We
obtain a crease which passes through the mid-points of the
remaining sides and is at right angles to those sides." p. 9

Nope, not that I am aware of either.  Actually, I don't expect publishers of

audio data (i.e. music CDs) will soon do that.  There are rogue sites on the

The issue comes down to the fact that the copyright owner/holder has the right
to decide how they want their materials distributed.  Unfortunately they may
act in ways that seem illogical or counter productive to "us" - but that is
their right.

The origami situation is compounded because of the somewhat independent nature
of models, though there are still enough diagrams for models that start out

There is nothing sinful about borrowing the book and making step folds (see the
archives for a description of step folds), or heck, even sitting in the library
and making step folds of the models you want.  Seems to me that if someone
really wants to know the model that bad, making step folds and/or their own
diagrams is not a substantial "burden."  As far as I can tell, the burden of
not copying only hits on someone who is harvesting large numbers of model
diagrams without any regard to whether they would ever want to fold them...

This isn't about "what we want" it is about obeying the legal and moral
obligations of copyright.  Copyright's purpose is to encourage publication.
There is nothing that says any creator has to publish any diagrams, and
copyright is a way to make sure that they will have some control over what
happens to their work.  If someone decides that their work should be lost, that
is their decision to make.  The only twist comes in when the copyright is owned
by a publisher who is not the creator.  Frankly I'd love to see a small press
that could cater to origami creators and allow them to retain their copyrights,
but I don't think it would be economically viable.  Perhaps
Publishing-on-Demand can change that.  But for anything already in existance,
the rules are the rules.

Oddly enough, it seems like Dover has been doing a good job so far.  Heck, even
BOS can't get its _own_ stuff back into print, and OUSA's '95 Annual Collection
similarly, so I wouldn't hold out any hope in that regard... The economics, at

Yup.  And it doesn't help that "the internet" is considered a "free resource"
many colleges offer free access and most ISPs have very reasonable rates, but
once you are "on" the information stupor highway, everyone expects content to
be free... (scarcasm ahead:)  Why, if it is so easily available, it must not be

In the case of Jeremy, most, if not all, of those models have appeared in the
B.A.R.F. newsletter.  B.A.R.F. is darn lucky that Jeremy cranks out models and
diagrams at the furious pace he does.  As far as I know, back issues are still
available (I haven't checked their web site recently) and contained models by
the late Mark Turner as well as Peter Engel and Robert Lang amoung others...  I
would like to be able to print diagrams in the Origami Club of Pittsburgh's
newsletter, but our club can't afford to pay for diagrams so we have little to
offer diagrammers in return for their work, except some amount of exposure, but
that is a catch-22 because outside of Pittsburgh folders, the only reason to
subscribe would be to get good diagrams.  But without a base of subscribers,
why would a diagrammer grant us non-exclusive rights to publish?  "That's some

I would reverse the challenge..... what about "putting" the ship in a TRUE
glass bottle ? What the best approach ? :-)

>>>
J.C. Nolan's Braided Paper
Although not completely flat (the center of the model has some
thickness), it certainly gets a wow from me.

Diagrams for both of these can be obtained at Alex Barber's site...

Could someone tell me what the "pleat sink" in step 8 is all about. I got
it up to there and if I ignore that step I make it to the end (but I'd like
to know what it is I should be doing ;-)).

Thanks,

Not always needed ! A smart e-mail program, like Eudora Light 3.0, does not
speak HTML (so HTML tags are left unchanged), but even without those tags
it DOES recognize URL's and makes them clickable (no color changes nor
underlining: you tell it from the cursor changing into a small hand). A
double click then opens the URL in the default browser.

Removing HTML tags from e-mail is not only a matter of netiquette: it saves
time and band width, much more than one thinks ! Have a look here for more
info's:

Edith, my name is Tobi and I make the math model, the vector equilibrium,
Buckminster's "jitterbug", my brand is the Vector Flexor.  I have been
lurking for months in this origami group. Now that this orthogonal question
is up I want to mention that I am now printing a poscard that has its roots
in folding the sq.  and this postcard (MORF FORMtm)  will fold into the
orthosheme for the cube.  Link 12 MORF FORMs (six left and six right) into
a torus and you have transforming geometry, morphology.  Edith, I like
getting these 2 items out into camps like you are the director of.  A
professor put a web page up for me at www.britestar.net/tobitoys.com  If
you add your zip code to your NY address I can smail you articulating
artfacts.  tobi...

Sheldon,hello, my name is Tobi and I make great things for home bound kids,
the Vector Flexor and now the MORF FORMtm.  they can be seen on a page a
professor put up for me at www.britestar.net/tobitoys.com  MORF FORMtm has
its roots in origami, but I print it on card board and have it precreased
so that it is easy to fold.  Link these little crystals together into a
torus and you have an articulated arifact.  Want a sample of the card? send
smail address.  tobi...

For a nice, clear essay on methods of dividing a square see the Tanteidan
subpage:

http://www.ask.or.jp/~origami/t/People/CAGE_/divide/index-e.html

Definitely one to print and keep within reach. The diagrams are nice and
clear.
