Cruising the channels on Origami Dan, I found a CP for a fold challenge I had missed, but decided to give it a whirl anyways:
Designed by Scott Okamura, this seemingly impossible fold featured a traditional Tsuru (crane) folded in the middle of a large page of duo paper – the surrounding paper is then formed into a box.

Apologies to Frankenstein lovers, but let us face it, this model is a bit of a Frankenstein. It is the result of putting a Satoshi Kamiya RyuJin 2.1 dragon head on a classic Tsuru (Crane)’s body. Nuts – right?
I first saw the CP (Crease pattern) for this on one of the Origami Discord servers I frequent (RyuCentral), and thought … how odd, how hard could that be??? Stupid man!
Dividing the paper into quarters and half along one diagonal, I reserved 1/4 on the diagonal for the crane and then set about laying in the graft CP for the dragon head in the remaining 3/4. It needed a 23 division grid that intersected at the square opposite the crane. Accuracy was the key. Grid laid in, I then started setting the pre-creases necessary for the head – stupid man, fucked the first set up twice (because I did not count), finally, pre-creasing done the collapse began.
I have folded many Ryu Jins, many versions, many times, so it was like returning to an old friend, interestingly muscle memory helped me not find the horrendously complex manipulations difficult at all (or maybe my subconscious was blocking the trauma) but to my surprise the accuracy I obsessed over early on paid off later allowing a pretty tidy collapse and NO damage to the reserved 1/4.
With the head collapses through early base, late base and shaping, I isolated and shaped the little arms and then set about working out how to fold a crane with the head as the head. Annoyingly I chose the wrong orientation first (der) and the head was upside down and backward. Just when I thought I would have to perform an infamous “neck twist” (interestingly NECESSARY on full RyuJins), I tried unfolding the crane and reversing all the creases (ie. folding it inside out) – to my delight that solved the problem (and THEN I remembered CPs are usually drawn WHITE SIDE UP – what a dickhead!!!).
Continue readingColour-change models are astonishing to me, designing models that use colour change are something special:
I have folded a number of different models like this, nothing quite like it however – what sets this model apart form any other is that each “tile” on the board is a seamless square.
Folding this from a SINGLE UNCUT square ends up being a bit of a brain-fuck. The paper was blue one side, white the other (actually cheap and nasty 70cm wrapping paper from my local dollar store). Distributing the “colour” is achieved, mostly, by bringing the sheet edges up through pleat bundles using a variety of techniques.
You can see the final location of the 4 corners of the original sheet in this development photo:
Planning/designing of a model like this is beyond me – pre-preparing the colour changes means that every bit of the paper has a job – either visible “tile”, spacer, flipper, mover etc to get the bits of colour to get where they need to go. Fold accuracy is the make or break of such designs – novices who use a “near enough is good enough” approach will not succeed here.
I was asked to test fold this, by Steven Casey, prior to publication. The diagrammed sequence is intense, starting with a 40×40 grid. Most of the folding is working on the wrong side, creating interacting pleat stacks that sit flat but that strategically manipulation pleat order. The run towards the “checkerboard” effect happens around the edges first, they they are migrated further towards the centre (although really only in a 4-unit strip around the periphery.

2: Amos who?
1: A Mosquito. <insert hysterical laughter of a little kid (me) amused by the first dad joke he can remember his dad telling him> True story.
I have bought many sheets of the most amazing paper, all dutifully stored in my “cave”. Over 10 years ago, I purchased a full sheet of black Unryushi single tissue because I HAD to have it, but having NO plan to use it.
Unryushi tissue is beautiful, painfully thin (24GSM) but gloriously adorned with visible mulberry fibres. It comes being about the stiffness of facial tissue – I misted a large window with water, rolled the sheet onto the wet glass (shiny side down) and then added a coat of MC (Methyl Cellulose) to the back side, removing air bubbles from the centre out.
Even wet, the Unryu is really strong, but to make it foldable I needed to crisp it up. I managed to cut a 60cm square, leaving a >12inch selvage for another project.
The latest Tanteidan magazine had a enthralling Mosquito design by Yoshio Tsuda and I knew I NEEDED to try it, but lots of the model is 12+ layers thick, I knew I needed some crazy thin paper … hence the Unryu. I decided to fold Version 1 of the Mozzie, knowing that Yoshio also published a crease pattern for his revised design – that will do for another day.
Continue readingGood paper is such a blessing. I took a long-stored square of olive Vietnamese Dó paper and attempted to fold a “Temple Dragon” – got most of the way through and realised the paper was too small/thick to complete it. Rather than bin the model, I carefully unfolded it, ironed it flat and … the paper had a new life:
Folding paper can damage it – wood-fibre-based paper takes damage (I call it paper fatigue) because the folding process can break the fibres along the crease. SOME paper has strong, flexible fibres that bend but mostly do not break, and Dó paper (made from bark of the Rhamnoneuron balansae tree) is astonishingly resilient.
The colour reminded me of something, as a kid, I used to see all the time – green tree frogs. Naturally I returned to Robert Lang’s “Origami Design Secrets” and re-folded his Green Tree Frog – I no longer had in my stored folds a copy of this lovely model so figured it was time.
Continue readingPerusing origami books, as you do, I chanced upon a delightful little pelican:
Designed by @tommy03, making use of a beige/white duo 6″ kami square, this delightful model captures the essence of a pelican better than any other I have seen.
“What a wonderful bird is a Pelican – whose beak can hold more than it’s belly can.” – A rhyme my mum used to say to me as a little tacker – hoping to gift this to another mother tomorrow.
Sometimes simple is stunning too.
There is so much happening in the world of Origami design, it is amazing to see new models emerging of every subject imaginable. I am working on editing/test-folding a bunch of Chinese diagrams currently, and thought I should fold this beauty to check on the sequence in the diagrams:
I started with 2x 45cm squares of Kraft – intending to fold BOTH the landed and flying versions of this model (yes – 2 different forms in the same model!), reached a part of the diagram I could not get past – I ruined, ragequitted and snowballed one of the sheets in frustration … only to realise the impasse just required a different view of the model.
Plunging on, through a challenging sequence, I muddled to the end and the result is quite amazing. I like that someone has focussed on the “on the ground” version of a model usually depicted in flight with wings extended. These critters were land dwelling, occasionally in the air, and their body morphology is full whack – prolly why they no longer exist (except as remnant critters like bats). Tapejara’s were thought to be particularly agile fliers and formidable predators, remnants of these have been found in Brazil.
This is part of an astonishing collection of new designs coming soon as a book from origami-shop.com and showcases some amazing layer /sheet management. I _almost_ want to go back and now fold the flying version of this model … almost.
Fun, challenging fold. I think folding this critter much smaller represents a huge challenge – the pleats that form the back legs/toes at this size ended up being 4mm – my fat clumsy fingers struggled to fold these accurately (and you form these pleats part way through the sequence – not in pre-creasing). Going smaller will be “interesting” for a more nimble folder.
A long while ago, a new artist on the scene, Fynn Jackson, started releasing astonishing mask crease patterns on social media.
He later commercially released his designs and I purchased his crease pattern packs for masks 1-35, along with the more recently released noses 1-9.
I love Fynn’s work, and eventually will develop my own CPs of faces. There is so much expression in the score and fold bundle, so decided to expand my collection and try out a bundle of manilla card in the process. I contacted @Jacksonorigami and asked him about selling finished masks – he (to my surprise and delight) freely encourages folders to monetise their rendering of his designs, so long as we do not share the purchased CPs (so please DO NOT ASK) …. so I got to thinking about an upcoming Gallery shoppe associated with my papermaker friends PAQ – put 1 and 1 together and arrived at 6.
I set about folding 6 faces I had not tried before from Fynn’s rich collection of characters, each using different aspect ratios, techniques and all quite wonderful. I was encouraged (by some of the wonderful ladies in PAQ – I am looking at you Ann and Wendy!) to consider selling, and began thinking about displays that would make them work as purchaseables.
Continue readingWhen I first read Frank Herbert’s “Dune” series of books, it was the mid 70’s and I was a teenager. The expansive universe captured my imagination like little else.
Dune Part 2 has just been released in cinemas, and the Denis Villeneuve adaptation is visually stunning. On planet Arrakis (Dune), a chosen method of air travel is the “Ornithopter”, described as an insect-like flapping machine.
’Thopters in the current movie series are astonishing, if illogical from an engineering perspective. Variously, ‘Thopters have 2 to 12 wings, each move independently in a coordinated buzz to provide controlled lift and thrust.
The origami world has a few simple ‘thopter designs, most modelled on the 80’s David Lynch film adaptation, so I thought I would have a go at designing one from scratch. Initially I thought to harness an existing base, but decided I wanted 12 wings, in groups of 3, and wanted landing gear, some paper for a fuselage and various flaps for some simple detailing.
There are many design methodologies I could have employed. Circle packing (each circle centre representing the vertex of a stickey outer bit), 22.5 folding to facilitate the point-splitting needed for so many separate flaps, but settled on box pleating.
First I sketched out a rough crease pattern (CP). 12 points along opposite edges of a square. The downside of this arrangement was the points ended up tiny – way too small for the wings. Rearranging them symmetrically allowed me to include extra flaps for landing gear, cockpit and more. Designing the collapse along a 2 unit strip of the central axis also gave me the bulk for the fuselage. I calculated I could achieve this with a 48 grid.

On Sunday during the weekend the PAQ “All Stitched Up” exhibition opened in Gympie Regional Gallery a fortunate group of paper makers were able to spend the day at Dion Channer’s paper mill. Michelle, Vanessa, Wendy, Sue, Heather, Ann, Joolie, Marjorie and me, Peter were in for a treat with Dion and his partner Sue Purnell. Surrounded by the bush, among music rooms and yurts, pavilions and lakes, Dion’s mill was a large shed with a bespoke collection of gear and infused with the passion of a master papermaker.
Over a morning cup of tea, PAQ members talked with Dion about individual goals and hopes for process assistance, we learned about the available fibres and equipment we would learn to use during the day. Following a tour of his eclectic property, we retired to the mill and began with an orientation.

Scrolling through this year’s JOISEL AWARD entrants, I noticed a lovely little Rocketship designed and folded by Zhu Yandan, from China – it was released with a crease pattern (CP) so I thought it worth a try.
I used a technique called “Ghost Creasing”, where ONLY the needed creases are transferred via careful embossing using a stylus. This eliminates the excess grid creases, making the fold cleaner.
Continue readingFor a system to be considered “Turing Complete”, it must be able to be used for completing any computational problem. In the world of DIGITAL Turing Complete setups, these computations are achieved using simpler binary operations (like NOT, AND, OR, NOR, etc.).
In a paper recently released by Mathematicians Thomas C. Hull and Inna Zakharevich, they propose flat-foldable crease patterns for origami “processors” that simulate a number of simple binary operations (namely NAND, NOR, AND, OR, NOT and a few ancillary operations) making the theoretical proposition that flat foldable origami is Turing Complete.
I folded a few of the paper’s logic gates, and made a video of how they work – have a look:
Although this is a little nerdy, I can at least conceptualise the idea that a network of interconnected origami processors could, theoretically, actually do something useful. Technical challenges exist with having such crease patterns co-exist on the same sheet, in sufficient quantities to represent anything other than single bits (0/1 or On/Off or True/False), but the idea is none the less tantalising.
I link to a copy of the paper here: FLAT ORIGAMI IS TURING COMPLETE
Everyone called Charlie Brown “Blockhead”, a past Deputy Prime Minister continually is caught acting like one, so I began wondering what that would might like:
I had recently folded Boice Wong‘s astonishing pair of figures called “Emptyhead” (I named them Dumb and Dumber), so started there, and re-familiarised myself with the crease pattern, devising a smoother collapse (as I adopted the much criticised method of “parachuting” the last time).
I briefly toyed with the idea of posing him like Neo during Matrix’s groundbreaking “bullet time” scene, but decided to go simpler because he would be a … simple … soul.
The tricky bit was to use minimal paper for a neck, leaving enough of a pleat tube to sculpt a 2×2 solid cube, and explored that geometry a bit before settling on a scheme.
Continue readingI had forgotten how wonderful it was to lose yourself in a fold, particularly an Eric Joisel design:
I decided it was time to re-fold Joisel’s Cat because … the last time I attempted it back in 2011 (as part of the original 365 project) she turned out barely recognisable:
Naturally, the cat is looking at something, I decided it must be a rat. There are few more character-ful designs than Joisel’s Rat, so I folded him again – this time on a sheet 1/4 the size of the cat (to sort of get the scale right).
I reasoned the rat was around for a reason, so quickly found Jeremy Shafer’s “Cheese” design and decided the rat’s next meal would be cheese (unless he himself did not become dinner for the prowling cat). I folded the cheese with a square 1/4 the size of the rat to sort of get the scale right.
All too often a fold is completed in isolation – few designers design “sets” of models that are sort of meant to go together. Joisel’s Cat and Rat reference each other in their diagrammed sequences – I like that. Both models have challenging sequences – each with places where your judgment on where a fold goes completely changes the attitude of the model – I like that also as it let’s you infuse character into the model, and often means subsequent folds look different.
I think the only other origami artist that comes to mind for designing “scenes” is David Brill – his masterpiece “Brilliant Origami” is full of fun tableaus.
The majestic “Bin Chicken” is, sadly, an aussie icon – those black-headed ibis emerge from the deepest, moistest corners of a ripe dumpster, dripping bin juice.
Yes, I KNOW that an Egret is not an IBIS (the beak is different and the body colouration is different… but… creative license). This is Jeong Jae Il’s “Egret” – a beautifully lifelike rendition of an altogether more polite bird. The diagrams, from “Potential Origami” suggest heavier paper, so I trotted out a lovely 58cm square of duo Yukogami to work this model.
The paper is stark white one side, jet black the other, heavily textured and light cardboard in thicknicty, but I thought I would fold until either it was finished or it failed. The only real struggle was thinning down the legs that end up being about 12-18 layers. In finishing, after dry-shaping, I slid a little white glue inbetween the layers then re-formed on my dry shaped form, compressed and found the paper dried solid – an added bonus was I did not need to add wire, she stood on her own!!
