793: (243/365) Jun Maekawa’s Tetra tetra

Looking for today’s fold, I returned to a collection of bookmarked models from my growing collection of Tanteidan magazines:

Made of 4 tetrahedral modules, each with deep tabs along a pair of adjacent sides, you then fold a pair of interlocking preliminary bases as the core. Continue reading

661: (111/365) Multiple Rippling Deltoid

I have passed this model many times, thinking “not sure what that is, maybe later”, but decided to give it a whirl tonight:

What a curious object. Designed by Jeremy Schafer, from his book “Origami to Astonish and Amaze”, this odd ripply mathematical conundrum hurts your brain to look at.

A fun paper manipulation first makes a nested tetrahedron, which is then accordion pleated to make the deltoid. You can then open it up like some surreal book, 4 separate rippled deltoids emerge – curious indeed. Continue reading

615: (65/365) Spheroid

Who could have foreseen that the concurrence of a series of parallel mountain folds interspersed between a series of concentric parabolic valley folds would result in something with such sculptural simplicity?:

This is Jun Mitani’s “Spheroid”, well, at least as close as I could get to it by guessing the intervals between parallel lines and the curve on the parabolic ones. Continue reading

Numbers? What Numbers?

I am often asked why some of my posts are preceded with a number. I must admit to folding paper, on and off, since I was 11, but more recently I took it back up again as a sort of physical therapy to convince myself (as much as anything) that I could control my nerve-damaged hands after spinal reconstruction.

The numbering makes sense to me, really. On January 2011 I (in retrospect rather naively) decided to try and fold a different model every day for a year. I numbered the models as I folded them, using that index to catalogue the unique folds I managed to achieve.

When I got to 365, I ran out of 2011 and no longer had the one a day madness that was actually really interesting.

I decided to keep folding. When I fold something I had never folded before it too is granted a number. I will continue – it is a useful metric for me, might be an organiser for you but it reminds me of the staggering variety of models out there, and reminds me of the fact that I have really only tried a tiny fraction of them so far.

Now you know …

500: Jackass

To celebrate the 500th unique fold documented on this blog, I thought I would hold a guessing game whilst trying a fold I have been considering for a while.500JackAss

This is “Horse Laugh” by Kunsulu Jilkishiyeva from Nicholas Terry’s “Drawing Origami Tome 1” – a fun fold that sees some amazing box pleating and layer management to make a really detailed head (with lips, teeth, eyes, the works), tail, rather lovely mane and some funky legs. Continue reading

458: Lang’s Flying Grasshopper = Jemima Cricket = WTF# 20

Sometimes I just need to fold, it is difficult to explain but I find great clarity in wrestling with complex geometry. We ALL have much to learn GRASSHOPPER. 

Having bought Robert Lang’s “Origami Insects Volume 2” I thought it was high time to fold something from it.

Lang’s models are great technical exercises, amazing manipulations of the plane to the extraordiary.

I am also searching for a model to use a sheet of Origamido paper I have on, but will not use it as a first fold – it costs too much.

There is lots to like with this model, and it was a good WTF exercises – sadly my origami friends probably recognised it immediately and my other friends had no clue.

457: Happy Book (WTF#18)

Fernando Gilgado is a legendary character folder, I have made many of his models, this one is a charmer:

from one sheet of paper, you get 6 pages, a hard cover, arms, legs, a smile and eyes peeping over the top – neat

So, as I mark furiously (having run out of the ability to put it off any longer), my procrastigami takes hold and I started bending something. I also wanted to try out my new self-healing craft mat (the green griddy thing) and have discovered that folding from an iPad or other tablet is better than a book because of the pinch-zooming possible to help old eyes see details of diagrams. Continue reading

456: L’essence d’un escargot

I was exploring a corrugation technique I last used with Eric Joisel’s Bandoneon and stumbled across a sort of plan to fold Joisel’s Snail:

You start with an extraordinarily long (my estimate – 3.25m) and narrow (in my model 9cm) strip of paper, then start folding slanted lines (using a 3:1 gradient) in both directions

Continue reading

455: The White Keep

In days of old, when people of a township were threatened they retreated (as their last best hope) into the Keep – a heavily fortified “core” of the castle that was designed to withstand the most vigorous of attacks

So I had this odd but interesting idea that it should, given the right size of paper, be possible to fold an entire castle from it. After being inspired by Gachepaper and his exploration of Lotka I decided to give it a whirl

Continue reading

449: Chaka Ryu

I stumbled across low res hand-drawn diagrams of a Ryu (Chinese dragon) and with a cursory glance said “why not give that a go”:

Two weeks later and a whole bunch of improvising helped me realise that may not have been a wise choice but I have something that is at least based on Hoang Trung Thanh’s model but not faithful to it.

On folding the range of pleats I added a ziggy zaggy spine, decided on 3 rows of scales and invented a method of locking the leg units (each leg is a separate sheet of paper) into the body pleats. I also stuffed the body (with neutral facial tissues) for a little shape and added a nice row of belly scales which I think make it look pretty nice.

The head instructions were un-followable (to me at least) so I sort of wrangled a new head with some lovely horns and a nice open mouth. Continue reading

446: Sunny’s Giraffe

Sunny’s birthday is coming up and she loves Giraffes:

In browsing for a suitable model, I discovered a Tanteidan containing a Satoshi Kamiya giraffe that I had not folded, so it seems it was meant to be.

I lke this model a lot – it is full of the essential giraffe features, economically uses the sheet and contains some wonderfully complicated folds. Continue reading

WTF (What’s That Fold?) # 12

I have a stack of Lotka that is just waiting to be folded into beautiful things, so I looked for something that would be suitable as a WTF (because it has been a while and my procrastinator is running on full right now):

Taking the largest square I could from a barely rectangular sheet, I pre-creased then began collapsing

Continue reading

440: Satoshi Kamiya’s Lion

I had one last piece of Nicholas terry’s “Tissue Foil” and a little time on my hands so decided to try and nut out Satoshi’s Lion:

This lovely little model is a right pain to fold – some astonishingly complicated twists and turns that are not really well explained in places – some of the odd sinks and manipulations to encourage the body shape were very challenging to understand.

After nearly completing it, I then decided to repeat the process with a piece of mid-tan Tant (newly purchased and arrived) and that also was a challenge – not because I was now unfamiliar with what needed to be done but rather that the paper was so thick that it became very difficult to complete folds.

I amazed myself by completing both – fairly happy with them – I learned lots along the way and, should I fold them again (and yes, I am not against the idea)  I think I can do a lot better, now that I know what goes where. Continue reading

438: Jason Ku’s Bicycle

Perusing a Tanteidan, I noticed a crease pattern challenge, set by Jason Ku, and filed it as a “that’s impossible” fold:

Needing to unwind from a hectic and punishing term at work, I cut a 55cm square of light weight Kraft paper and set about working out, geometrically, where the myriad of creases were.

Although there was some regular geometry to place landmarks, there were some “mystery meat” creases that I just sort of fudged really – professionals would have measured it but I know I am an amateur.

Continue reading

WTF (What’s That Fold?) # 8

I saw this AMAZING design, and figured it could not possibly be made out of ONE SQUARE without cuts, or glue and became determined to try and make it for myself:
I found a crease pattern but little else to go by, so sort of wrestled the initial creases into place as best I could. Continue reading

436: Sydney Opera House

Anyone who knows me understands my fascination with the Sydney Opera House, as a kid I saw the sails of it being built:

Set magnificently on Bennelong Point right in the heart of the harbour, it together with the Sydney Harbour Bridge (no, do not panic, I am not making that) are quintessential Australian icons.

Googling one day I stumbled across a design idea from Gerwin Sturm (2007) for a box pleated version of my fav building on earth, and some vague explanations of how it “should be possible to collapse and shape based on a 32×32 grid”. Continue reading

WTF (What’s That Fold?) #7

…so it has been a while I know, and it is raining, and I am too lethargic to do much more than bend paper so I thought it a good plan to do another WTF competition.

This fold is experimental in that I only have a kinda-sorta vague idea how to do it, but will bend it like … well … me I guess

After taking a 70cm square (yes, it is HUGE) and dividing it up into 32nds horizontally and vertically, I lay in some odd diagonal zig zags (you can make them out if you squint one eye, close the other, raise your left leg and hop on the spot), you get to this (the stage before the first round of collapses:

Continue reading

WTF (What’s That Fold?) #6

Ok boys, girls and small green aliens from alpha centauri, I present to you clues for this week’s WTF (What’s That Fold?) also model #434

I start with an enormous square (using a square cut from an a1 ish sheet of litho, no idea if it should be nice side up or down so I just guessed. Using the ourPAD as the repository of instructions and not yet known if I will need anything from my origami toolbox:

Continue reading

WTF (What’s That Fold?) #5

For this week’s WTF (What’s That Fold?) #5 we go to a Japanese Designer.

I thought I should try something easier to guess (but harder to fold). This model is complicated (has over 100 steps) but the end result is really obvious

Continue reading

430: Lang’s Spider Conch

Those of you who were guessers for the WTF (What’s That Fold?) #4 will be interested to know that this model was actually a Spider Conch designed by Robert Lang:

I once taught on Palm Island – which is seaward from Townsville, North Queensland. Whilst there I loved to snorkel the reef nearby. Whilst doing so, I managed to find a pair of “spider shells” that I still have today.
