As part of the privilege of test-folding models for a forthcoming book, I also had access to brilliant new designs. I decided I must fold one of these for myself:
This is “Star Virus”, a relative of “Space Virus” that I had already folded (from his previous book) waaaaay back in 2020 at the beginning of the global pandemic.
The form of this kusudama is glorious – star-shaped protuberances from a glorious faceted sphere – reminiscent of the most popular visualisation of the Covid 19 virus, I decided to fold it in royal purple and yellow because Covid is mutating all the time, and this I see as a mutation of the original in every way.
They say “if at first you don’t succeed, mutate and try again” seems to be the pandemic trajectory – this model has modules that are refined, positively lock and the whole spikey ball was such fun to fold.
Test folding is different to model folding, the brief is to see how easy to follow the diagrams are, how reproducible the forms are and what sense the written instructions make.
As all the models in this book are unit-based, I folded 3 or 4 of the modules (rather than the entire 30+) to check the 2 types of joins and how regular the construction methods can become. There is a wonderful mix and variety of spikey balls in this new (as yet unpublished) collection, and the skill levels to complete them range from fairly easy to nearly impossible – which is good, challenges abound for all levels of folder competence.
Unit and join testing – 3+5joints (“Star Virus” kusudama)
Xander commonly uses some funky paper ratios in his base-papers. Commonly 1:root(3), but this collection uses 2:root(3) and more exotically 6:5root(3). The paper ratio allows construction of accurate angles (many based of multiples of 60 degrees), and the book demonstrates nicely how to cut sheets of this ratio from more conventional sized paper.
Each kusudama has it’s own quirks, tricks and stress points, all require accuracy and nice paper (most showcase duo coloured paper in flamboyant and wondrous ways).
I have not folded a book “cover to cover” since I was a kid (who only owned a only couple of origami books) – it was an intense but hopefully useful journey as I made notes about the instruction set, unit folding and assembly process, subsequently passing this on to Xander for his consideration.
As I approach retirement age, I can see myself doing more in the meta origami world, having already established myself as an origami book editor and test folder – having time to do this without having to shoe-horn it inbetween school commitments is a luxury I am looking forward to.
I am always looking for folding (and prograstigami) projects, my friends often )helpfully) suggest I “fold the washing” – my question to this is always “into what?”:
This lovely little colour change model is in the latest Tanteidan Magazine (one of many advantages of being a member of JOAS.
Designed by Motoo Ohguchi, I decided to punish a lovely 21cm square of Shibori duo paper, and set about the exacting divisions, colour reversals and smoke and mirrors that form the shape and details.
The layers get really dense, so thin paper (or going large) are solutions – I tried it on 15cm Kami and struggled to shape the collar and other details at this scale and thickness.
An invitation went out on Fakebook to join a “fold along” session with Fergus Currie and, although it was after 11pm local time I thought why not:
Fergus taught the module then construction of a 4-part modular Frustum (a truncated pyramid) – an ingenius and “frustrating” model in that the lock between modules is accomplished using a “latch crimp” tab inside the bent gusset pocket, making the actual construction a little fiddly.
I found I needed to ease the 3rd and 4th modules in place using long-nosed tweezers, when it sits right it locks tight but requires a bit of a controlled jiggle to get it to be seated just right. The final module is a bit of a challenge to insert without dislocating the two either side of it.
Patience and tweezers finally won over and the top half finally was locked tight and tidy, then a simple weave on the bottom flaps complete a lovely truncated pyramid. Material thickness is an issue here – the tab-pocket system assumes material of negligible thickness. If you use heavier paper you need to fractionally adjust either the pocket depth or the tab length – fortunately there are a couple of fold junctures that make this easier.
Anyone who owns a lawn realises it is a constant battle to keep it mowed, tidy, healthy and weed free. In a tropical climate like ours, doubly so:
So we have a dandelion problem – hundreds of the little buggers pop their flowers up after I mow and I am loathed to resort to spraying them, chemical solutions are my last resort. I googled the problem and found a no-bend weeding prong that seems custom built to pluck the little suckers root and all.
We ordered 2 (a his and hers set) on the off chance we both would want to do this, the arrived in pieces and after a simple set of instructions they were assembled, ready to go. In our first session on the lawn we easily filled a large bucket with extracted dandelions and realised this was a solution, albeit manual and long term.
In the latest Tanteidan magazine, by pure synchronicity, there were diagrams for a modular dandelion designed by Toshikazu Kawasaki. I set about folding the pieces and, after a fairly simple set of instructions, the dandelion was assembled and ready to go.
Having recently purchased a bumper pack of 6″ duo paper, I was itching to fold something with it. Given we are in a new wave of Covid-19 (Omicron), I thought a virus-like kusudama was in order:
This is Xander Perrott’s lovely modular design “Minaret”, a 30-piece ball of wonder.
Each piece is based on a 1: root(3) proportioned rectangles, intricately collapsed into beams with tabs/pockets on each end.
Looking for a model to welcome in the new year, and also to further my Crease Pattern solving ability, I hoped this model would serve both purposes:
Part of a book I have helped edit prior to publishing, this is 1ctzH8jm0N2’s “Bone Dragon”, a CP and photodiagram sequence from the forthcoming book “Ori-Fancy 6”.
I started with a 90cm square, I divided into a 32 grid, then located the required diagonals, then begin allocating mountain and valley orientation to the creases before attempting the collapse.
There are lots of details here, and the initial collapse generates most of them – I buggered up the head collapse (rather I found the intricate point in point structure that would eventually become the horns too hard to do initially) but found it easy to do post-collapse, and was initially flummoxed by the feet structure until I realised a series of sinks needed to be closed-sinked, and another set needed to be open-sinks (hopefully this will be made clear in the final photo diagram annotations).
The body ends up being 30+ layers, making the necessary crimping for shaping really difficult with thick paper (I used natural Kraft paper) – there is a nice “bulk” to the body, and the body feels solid – thinner paper would make shaping less torturous.
To celebrate the release of his lovely new book of modular polyhedra (must get me one), Fergus Currie offered an early morning (for me at least on the opposite side of the planet) workshop on how to fold his second stellation of a cuboctahedron:
I set an alarm, awoke at 1am and folded along with Fergus.
I like this modular a LOT – each vertex is a single piece of paper – it works well with paper that has only one side printed or printer paper. The design is ingenius, the angles odd and exacting but you get into a groove and they make sense in the end.
I went into production line, and using the template to establish the initial odd division, I found that using a fine ball stylus and ruler it was easier to lay in the intermediate creases with the accuracy to make the vertices crisp and accurate.
Once I had 24 units, I then interlocked them in groups of 3 using the narrow tabs and pockets – these interlock really tightly and I could not imagine trying to do these later. I then joined the triples as they tile on longer tab-pocket sets that slide together with a little encouragement. Eventually the units combine to become this wonderful spikey ball with unique geometry.
One of many benefits of being a member of Origami USA (OUSA) has been the “Origami Connect” online classes program. For Christmas, members were treated to a free workshop with Riccardo Foschi, who taught his delightful “Sitting Gnome”:
Due to the tyranny of international timezones, their 1pm EST workshop meant I had to join them 15 hours later (for me, 4am the day after). It feels weird to be in their future, but there you go. I set an alarm, made a cup of tea, folded along then attempted to go back to sleep again afterwards (fairly unsuccessfully, annoyingly).
This model is a lovely figurative representation of a gnome – hat, nose, moustache, beard, stubby body and stickey outey legs and feet – a little like the “elf on the shelf” idea – it is a pity he has no hands (I might mess with the design a little as there is LOTS of paper not doing very much that I may be able to encourage some arms from).
Riccardo was a delight, his models have a real cuteness charm, and he is very generous sharing CPs with the community, many of which I have folded, I love his design sense, and the fun his models are to fold – often cartoonish happy things they are.
Clocking on for another round of procrastigami, I decided to give the first of the “twister” series a go:
Twister A – 2×2 molecules
This is “Twister A”, designed by Ilan Garibi, a lovely dimensional fold with a final twist to finish it off.
I have folded a few square twists, this one perches a twist on top of the intersection of opposing ridges, contains remarkably few folds on top of the base square grid.
Twister A Single Molecule
The basic molecule tiles awkwardly – because of the directionality (it forms in a clockwise direction) of the molecule, you have to reverse adjacent molecules if you want them to line up.
Exploring Ilan Garibi’s lovely book “Origami Tessellations for Everybody”, the next “family” of folds starts off with “Childhood” and then evolves into more of the same:
Childhood-Evolved (4×4 molecules)
This is almost a corrugation, as there are nearly no layers overlaying others – the surface treatment is deliciously dimensional, and the distortions are caused by paper tension and torsion of the underlying square-twists.
“Childhood” molecule
I started with standard cotton-based photocopy paper (which for me is a LOT like thin Elephant Hide) and laid in a square grid. Both childhood and childhood-evolved use off divisions. I folded a regular division (halves or thirds), then halved until I was close to the required grid sizes, then sliced off unneeded units before laying in the wedge-shaped mountain creases.
This is ‘Red Flower’, the base fold of which there re many variations, but the base molecule is based on a square grid and (for single molecule at least) simple to pre-crease and collapse.
When you scale up, accuracy shows itself as important – slight errors mean that the internal collapses twist the whole sheet out of shape.
Looking for something to de-stress and unwind to after a brutal term, I turned to “The Works of Satoshi Kamiya II”, and a model that I was astonished to find I had never tried – his hermit crab:
Starting with a 70cm square of natural/white Kraft paper, the fold was challenging as you allocate one side of the sheet to the crab, the other to the shell. Via a fabulous fold sequence, you tease legs, claws, antennae, eyes and mouthparts while delicately colour-changing the rear and then spiralling a shell as his home.
This is, (der), genius design – I always am amazed with Kamiya designs, and the elegance of the developmental sequence – as if the journey is every bit as delightful as the destination.
I am trying to get my brain back – the term has been brutal so I decided some paper therapy was in order. I originally folded this model back in 2011, on tiny paper, and the resultant mess was posted as part of that year’s 365 challenge.
I had vowed to re-fold it with better paper, and I decided to do that today.
I cut a 50cm of pearl coloured Lithography paper, and carefully followed an instruction set that only lasted 103 steps or so (quite quick for a Kamiya model).
I love how this horse seems to emerge from an otherwise non-descript tangle, with glorious and sensibly placed, appropriately muscled wings.
When a legend graciously shares hand-drawn diagrams for a lovely simple Eastern Dragon, one simply has to give it a go:
This is an “Eastern Dragon” – interestingly most people in the west believe you need to staple wings on such a critter so that it can fly. Our eastern cousins accept that this sort of critter can fly, wings are not necessary for this activity.
This design was recently shared, luscious hand-drawn diagrams from @brianchandesigns, a gracious and fabulous gift to the origami community.
