1067: Watermelon Colours

So to avoid doing the growing list of things I should be doing, I decided on some procrastigami:

Xander Perrott's Laveau

One of the many “I must fold these” models from Xander Perrott’s forthcoming books, this is “Laveau”, a lovely 30 unit spikey flower ball that makes good use of duo paper.

Each unit, based on a 1:root(3) rectangle, folded from Tuttle Vibrant duo, I chose limey/crimson paper and began folding – I always love the almost meditative state you enter when unit folding on a production line – much the same as gridding before box pleating and tessellations.

1066: Star Virus

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:

Xander Perrott's "Star Virus"

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

Over the last couple of weeks I have been granted the privilege of test-folding the models from Xander Perrott’s new Kusudama book “Angular Elegance”:

Models 1-20 of 22 - 3-join
the 3-join of models 1-20

I bought Xander’s first book “Folded Forms”a treasure trove of delicate spikey balls. I offered my services as a test folder – to my delight and amazement he said yes.

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 There is a wonderful mix and variety of spikey balls in this new (as yet unpublished) collection, and the skill levels to complete them range from fairly easy to nearly impossible – which is good, challenges abound for all levels of folder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.

1064: Fergus Currie’s “Frustum”

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 Currie's "Frustum"

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.

1062: Omicron

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:

Xander Perrott's "Minaret"

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.
