The traditional hat-to-boat from a rectangle forms a regular part of my teaching classes. It’s fairly simple, involves some nice “in the air” open & squash folds and makes a superb boat with sail. I also regularly take newspaper with me to deliver the classic “captains shirt” story, which never fails to amuse young and old. There’s some more useful info about the model here.
One method I often employ to reinforce learning of a design is to have students fold it again from paper half the size. They then repeat this process and a friendly “how small can you go” competition often ensues. The boat is perfect for this and you can also introduce the concept of A4 / A5 / A6 etc. if you wish.
The boats also tuck neatly into each other, providing you fold such that a decent sail is produced. I’m sure you know, but the ratio of sail to hull is determined at an earlier stage, when you fold up lower corners.
Folding to the top produces a sail level with the top of the hull. Folding less than this distance produces a sail. Eventually, the hull is tiny and the sail huge. Encourage the students to investigate the possibilities.
A few years ago I discovered a development of the boat, one which I haven’t seen before, although the chances are it’s already “out there”. You perform another “open & squash” move, swinging each end of the hull in opposite directions and you have a fish. Neil Calkin points out in his comments that you can take it at least one stage further, producing a kind of gondola, although this may well be beyond the capabilities of a novice folder. Further iterations will depend on the thickness of your paper!
These ideas further extend the possibilities of this sequence, (providing you don’t tear to form the t-shirt!) allowing you to make “sea” montages by using a large sheet of blue paper, drawing a line to represent the horizon, and adding boats (and birds) above the line, fish below. A sharks fin is easily formed by folding a square in half, try setting this as a creative challenge.
I came up with a module recently (on the day I was invited to the UAE to teach, hence the name). I’ve made diagrams, but that would make life too easy for you all, so here’s a photo showing the nearly completed unit, plus a couple of possibilities from it. The central “diagonals” can easily be removed. Any of the “Sonobe” configurations should be possible. Let me know how you get on with it!
It’s fair to say I’m obsessed with origami dishes / containers. I’m regularly ribbed about it when I volunteer to teach at a meeting (“not another Shen-like Dish Nick?”). However, I’m unrepentant – a man’s gotta fold what…
However, when it comes to containers, nature has us beaten all ways. The egg shell is perhaps natures most perfect container, but seeds of any kind are impressive. I found this chestnut whilst walking in the park yesterday. Not only is the outer shell superbly designed, but the inner seed is a real jewel. This one had two “conkers” within, each a gem of perfection.
So, in all modesty, I thought I’d display them in one of my own containers, Ali’s Dish #2 – a development of Ali’s Dish #1, featured in LaFosse’s “Trash Origami“. Ali is my long-suffering origami-widow who is undoubtedly thrilled to have a model named in her honour.
They’re perhaps not directly comparable, but I hope my quest for simplicity and beauty in origami mirrors evolution in nature. And yes, evolution is real, despite this wonderful tome from late 60’s America – don’t let anyone persuade you otherwise…
My daughter received this folded envelope containing a free sim card today. The design is traditional and well-known, but this is the first time I’ve seen what must be a substantial use of it. As with all these types of commercial folds, I wonder who actually did the folding?
Below are diagrams by Matthias Gutfeldt from his site. used one of his paper plane designs in a book many years ago and since he hasn’t updated the site since 2004, I guess he won’t mind me poaching the image!
At a mini-meeting in Hazel Grove (near Manchester) yesterday, I re-learned a model from the distant past. I can’t remember where or when I last saw it, but it’s a 6 piece modular made from a blintzed bird base.
This got me thinking about the BBB, which few of the attendees at the meeting seemed to know about. Back in the late 60s, the BBB was seen to be the ultimate base – you could make almost anything from it – dragons, horses, beetles, even a grand piano (Pat Crawford). When I started folding in the early 80s, it was still a talisman for beginners. Who would ever want more points from a base? How naive they were 😉
To make the modular, sink the top triangle by half its length, then fold each of the four lower flaps to the top. Open each flap out at right angles to the next. Form a ring of four, ticking corners under sink edges, then add two more to form a cube arrangement. It holds together reasonably well, although smaller versions are tricker to assemble without glue. Almost a joke there.
I did a quick google and found no immediate diagrams for either the module, or surprisingly, the BBB itself, although it’s used in passing here http://www.barf.cc/nuccrane.pdf As you can imagine, it’s a square, blintzed, from which a bird base is folded. The blintzed flaps can then be eased out again. The method I prefer, created via a waterbomb base, is shown below.
update : I’m told the unit is by Nina Ostrun and is diagrammed here although I still feel in my bones I’ve seen it a long time ago.
I’m deciding which folds to make for the exhibition table at the York BOS convention tomorrow. I always agonise over whether things are worth displaying, since my tastes veer towards the simple side and put next to an ultra-complex model, the two styles don’t quite complement each other.
I’d be tempted to arrange tables by complexity, so like can be compared to like. Here’s one I’m taking – I finally found a use for the pack of “opalescent” paper that’s been gathering dust for years – gaudy but effective 😉
Here’s a couple of pages about my work with masks, published in the Oru magazine in Autumn 1993. I never dreamed what extraordinary work Joisel would soon produce! (Click to enlarge the image)
I have a large box of discarded creative efforts and from time to time, I wade through them, seeing if anything actually has promise. I’ve had a twisted flower for about 15 years, but it was just that, twisted but not locked. A flash of inspiration later, it’s elegantly locked. Changing a key angle allows variations from tight to open. No actual method yet, but I’ll teach it at the forthcoming York BOS convention and see what happens!
I was taught this box by Erica Thompson at the last Sheffield maxi-meeting, using “roller blind” paper. The lines of development from the Kawasaki Rose are clear, but it’s not just another clone. I found it fiendishly difficult (being old and out of practise), but the result was well worth it. I gather there are a couple of variations out there.
I’ve just been sent a copy of the AEP’s magazine, which includes a “catamaran” design of mine. Or rather page 1 of the design! I guess page two was lost in the ether somewhere, but I wonder who decided the last step of page 1 represented a finished model? It’s flat for one thing, but they drew a little “finished” illustration anyway.
My reputation will clearly be injured by this and I’ll be seeking restitution through the International Court of Justice in the Hague. In case you’re interested, this is how the completed model should look.
