RUFF & HiDEF Meetings Report: March 2014

//////  Two folders attended the March 2014 RUFF (Rosamond Upbeat Folding Fanatics) meeting. Two folders attended the March 2014 HiDEF (High-Desert Enthusiastic Folders) meeting.

Origamies we folded in March: (1) Sonobe Cube & Jewel  (2) Three-Piece Spinner  (3) Square Spinner (4) Flower Tato  (5) Umulius Rectangulum  (6) Samurai Helmet  (7) Petal Cube  (8) F-14 Tomcat  (9) Gaillardia revisited.

1.  Sonobe Cube & Jewel.  Design by Mistunobu Sonobe. Diagram can be found in various books and on-line sites. Two books are “Beginner's Book of Modular Origami Polyhedra - The Platonic Solids” (2008, pg17) by Rona Gurkewitz and Bennett Arnstein, and “Modular Origami Polyhedra” (MOP) by Simon, Arnstein, & Gurkewitz (1999, pg12).

MOP shows the Basic Cube and the model often called Toshie’s Jewel, supposedly named for, or designed by, Toshie Takahama, although I’ve seen some comments that this is not true (I don’t have a specific reference for this assertion). In MOP, on page 12, it is called “Toshie Takahama’s Jewel”. The Cube is made from 6 uncreased (ie, flat squares with flaps) Sonobe Modules. The Jewel is made from three “back-creased” Sonobe Modules (ie, creased in the opposite direction from that used to make the Dodecahedron and Icosahedron); then you wrap the three modules around each other to form the jewel-like shape.

The basic Sonobe Module is simple and quick to make. Many variations have been designed by other people. Eight variations are shown in MOP, and there are many others.

2.  Three-Piece Spinner.  Diagram in “Origami for Children” (2009, pg22), by Mari & Roshin Ono; a note in my book says the model “is attributed to Aso Reiko ca 2012”, but no source for the attribution.

The Bottom Piece is made from what I call the traditional Coaster Base. Many flower models and other decorative models are made from this base, which is the Windmill Base with all four “flaps” Petal-folded. The Middle Piece is two Book Folds, then a Full Blintz, turn over, 2nd Full Blintz, turn over, 3rd Full Blintz; tuck into Bottom Piece. The Top Piece is two Book Folds, then a Full Blintz, then a 2nd Full Blintz, then a 3rd Full Blintz (no turning over); form a Triangle Base (flaps inside) and tuck the points into the Middle piece. Spin. I first learned this model from Bennett Arnstein, probably in ca 2004.

Here are two Spinners, showing the top:

And showing the bottom:

And here’s one doing its spinning thing:

3.  Square Spinner.  Design by Yami Yamauchi. Diagrammed in “Origami Square Spinners”, a PDF booklet by Bennett Arnstein (2008), available as a download from OrigamiUSA. The book includes patterned pages that can be printed and folded to make spinners that make your eyes go round. You can also draw or paint on your finished model. The model is made from a non-square rectangle (8.5x11 works just fine). A fun, simple model to teach and fold at parties or other gatherings of people wanting to have fun.

Here’s what the top looks like (hand-drawn design):

Here’s the bottom, or back-side:

Here’s another one, made from some scrap paper, with a hand-drawn design:

Finally, one in action:

4.  Flower Tato.  Design is by Loes Schakel (Netherlands). Diagrammed by Kees Schakel and available as a download from OrigamiUSA. There is one error in the diagram, as of 2013: at step 6, the dashed line at the top of the drawing is drawn in the wrong position; it should be vertical rather than horizontal.

The folds are somewhat challenging to understand, but once you have it, they are not hard to do and the finished model, which can be opened and used as a small envelope, is very pretty, especially when made with Duo Paper (different color on each side of the paper).

The front side is the tato, or envelope, that can be opened “with a twist” and a small, flat item tucked inside. The back side can serve as a picture frame, if a photo is tucked under the corners.

Here is one made from the cool black-and-white paper I bought at Michael’s Crafts. This is showing the envelope side:

Here is the back side, showing were you could insert a photo:

And one made from red-green duo paper:

Back of red-green model:

5.  Umulius Rectangulum (Impossible Rectangle). 
Design by Thoki Yenn. Diagram by Dan Kalmon at:

This site is the re-hosted Thoki Yenn site (Mr Yenn is deceased). Andrew Hans (via OUSA/PCOC 2013 model bibliography) also cites a diagram in “World's Best Origami” by Nick Robinson.

I found two videos for this model, one done with paper, by Sara Adams, and one done with dollar bills by someone called Thebigbluevan. The one done with paper is the original (per the “thok” website) while the one done with dollars was adapted/designed by Andrew Hans. Andrew is also the person who taught the model at PCOC 2013. The original used a unit of half an A4 sheet split the long way. See the “thok” site for more information.

The video sites are (first one is done with $$ bills, other is done with paper):

The “” site (the “thok” site) noted above also has a link to another variation by Jim Cowling, using just 3 pieces of long-ish paper, one piece for each rectangle instead of two. The website says the name Umulius Rectangulum is Danish, “umulius” being the term for an impossibility or an “impossible” person.

I dub it a High Intermediate model. The folds and the assembly are both challenging, requiring good accuracy, nimble fingers, and patience.

A friend who attended this meeting, walked me through the folding and assembly. The photo is of the one I made and it shows its “good side”. It didn’t all fit together nicely on the back side. The way the corners collapse into place, if the pre-folds are done well, is pretty cool; they snap into place with just a nudge.

Photo of Umulius Rectangulum, folded by Chila:

6.  Samurai Helmet.  Design is Traditional. This model appears in many books. Step-photos appear on:

Starts out like a Paul Jackson Mouse, but color-out. This is a Simple, Traditional model that makes a nice decoration or can even be worn, if made from large paper (18-24” square).

In the photo, the one at the top is the traditional configuration. The other three were folded slightly differently, just for fun.

7.  Petal Cube.  Design by Unknown. No diagram known. I learned the Petal Cube from someone at a WCOG meeting, in ~2008. It’s made from a base that is a minor variation on the Four Sink Base diagrammed in Meenakshi Mukerji’s “Wondrous One Sheet Origami” (2013, pg 21). You use the triangular “flaps” on opposite sides of the resulting square to insert into opposite “pockets” on adjacent modules, creating a 6-piece cube of the back-color, with petals of the front-color at each corner (or the reverse, depending on which side you start with).

I have never seen the exact same model that I call “Petal Cube” pictured anywhere nor an exact diagram published or posted, so don’t know who might have designed it.

The modules are Low Intermediate, but quick to make, and the cube is easy to assemble. There is no lock, so if you want it to be tightly-assembled, you’ll have to use a bit of glue, but as long as you don’t toss it around too much, it stays together pretty well.

Hang it with a thread, and a bauble hanging from the bottom, and it makes a beautiful kusudama-like decoration.

This one is made from pretty duo-paper, plain color on one side of the paper, print on the other side. I used two different papers, one green and one pink, for variety. Here is the pink side:

And the green side:

And this shot shows both sides, where they come together:

8.  F-14 Tomcat.  Design by Michael LaFosse. Diagrammed in “Origami Art” (2008, pg 125) by Michael G LaFosse and Richard L Alexander. The model is also published in at least one other book by LaFosse, plus I have his original “F-14 Tomcat” (or “Aerogami”) pamphlet printed in 1984.

The LaFosse F-14 (a U.S. Navy fighter jet) is one of my all-time favorites. It’s not that hard to fold, but does require a high degree of accuracy to fold nicely. I also think it’s one of those models that is just “fun to fold”, and has a lot of “wow” power (it never fails to impress).

The stand I sometimes make for it was designed by John V Andrisan (who originally taught me the F-14). He bought a copy of Michael’s pamphlet in the 80’s, from a Popular Science magazine. I got my copy (almost the last one; when I later looked for another, they were all gone) in 2005, when I visited “Origamido”, the storefront and studio of Michael LaFosse and Richard Alexander in Haverhill, MA.

The model is especially nice made from black, gray, or white same-color duo paper (same color on both sides).

This one is made from the black-and-white patterened paper mentioned above:

Here’s the underside, which I think is just as cool-looking as the top-side:

9.  Gaillardia, revisited.  This stunning model is diagrammed in Meenakshi Mukerji’s “Wondrous One Sheet Origami” (2013, pg 59). The original model shows both sides of the paper, but I fold it in a simplified manner that only shows one side of the paper, so it’s best to have a print that has something interesting in the middle of the square. I call the resulting model the Non-Color-Change (NCC) Gaillardia. Everything you see on the front of the flower is from the front-side of the paper, whereas Meenakshi’s design shows the color of the back-side in the middle of the flower. See her diagram for more info. Her book is well worth purchasing; it contains many other really nice one-sheet models for your folding pleasure, some of which I hope to feature at my local meetings in the future.

I think the original model is High Intermediate, and my NCC version is Intermediate. Both versions require a high degree of accuracy in the pre-folding to do nicely, and it also requires a collapse and some sophisticated petal-shaping. The original model also requires additional pre-folding and working with the paper in several layers; it’s best done with larger paper or relatively thin, crisp paper.

The NCC version makes use of some of the steps from Wenhau Chao’s Emma’s Secret Star (ESS) to simplify the folding while achieving the same look in the finished model, but without the Color-Change.

Video instructions can be found on, by Sara Adams.

First photo is the original Gaillardia (showing both sides of the paper), made from gold foil, white paper on the back. The gold shows up on the petals and the white back-color shows up in the center:

This photo shows the back of the gold-foil Gaillardia. It does look messy, but only because I did a poor job with some of the pre-folds:

Last photo shows an NCC Gaillardia, made from some gorgeous paper I bought recently from OrigamiUSA. It has lots of color and pattern (it’s called “kaleidoscope”) and the center seems made for a model like this, which highlights the center of the paper. Only the front-side of the paper shows in this version of the model. The model makes a lovely pin or brooch:

All Photos by Chila Caldera, unless noted otherwise. If you use them, give full credit, for the origami design and the photo. If you use any Diagrams on this page, or pointed to, give full credit to the extent known, for both the design and the diagram; you may share, but not sell, the diagram.
