Playing with geometry, it got me thinking about lampshade forms. Correct me if I am wrong but there are the sort of “hang-down” and the “stand-up” types common?
Using 15cm Kami, I began doodling, the blue square form came first – a simple corrugation on the middle half of a sheet, folded in eighths only in the middle section it curves perfectly and creates a rather regal “ruff” – imagine nice/interesting/handmade paper and diffuse light in the middle of that.
Researching tessellations, I stumbled across a paper, written by Helena Verrill (Queens University, Kingston, Canada) that generally introduced the concept and looked at a number of common tiling patterns, but the first CP is one I had not seen before:
I did a small tester and loved (fluked) the collapse, and decided to scale up to a full A3 sheet, starting with a square grid. Then nested adjacent squares are layed in on diagonals to provide odd inverse hinges.
I am quite happy with this, and if more ambitious, I would fold it much smaller on a larger sheet – it would make amazing dragon skin.
One of the interesting things about being associated with “Pinterest” is that their algorithms continually look for stuff it thinks will interest you. Given I only browse Origami, I get some interesting leads. I saw a triangle-based tessellation/corrugation and did a little digging:
Seems Ron Resch, in the early 1970’s, was heavily into paper-based corrugation and this design emerged around then. The basis of this fold is 2 triangle grids, one at twice the scale of the other, offset at 30 degrees to the other. It took me a couple of failed attempts to get the crease layout to work but in retrospect is is much simpler than it seems.
Over the last few years I have played with origami tessellations – the theory of a repeatable pattern that interacts with other repeats (molecules) is fascinating and a real testament to the accuracy of the pre-folding. As part of another project, I have been exploring triangle grids, and a devilishly tricky to collapse hex-cell tessellation by Robert Lang he calls “Honeycomb”.
After folding this a number of times, and then schematicizing the molecule, I noticed that “cells” were deep and, due to the nature of the collapsed layers inside I did not think they were very tidy nor kept their shape nicely. All to often, in origami design, paper thickness is disregarded in the theoretical collapse – in this case hiding away most of the paper in canyons between cells deforms them in ugly ways.
I started playing with the corner mechanism, and discovered I could halve the height of the cell wall, making the tuck much less bulky and doubling the size of the resultant folded field on the same bit of paper. Additionally it held itself together nicely with edges that are easy to stabilise. With a little practice (I am sure my work colleagues thought me obsessed, given the number of times I folded this tessellated field) I was ready to scale up … well, down in truth as I folded a “tiny” triangle grid on my target mustard leather-grain paper and then set the corner widgets before collapse only to then realise that folding this small was a real challenge with my nerve damaged, fat clumsy fingers.
The international origami community recently learned of the death of Frances Ow:
Francis was an active and beloved member of the Singapore Origami group, and sadly I never had the privilege of meeting him in the real world. But, via the magic that is the Internet I have been personally encouraged and supported by him over both of my recent 365 challenges. You can try this Tsuru Wreath for yourself – one of many designs he shared freely. [more of this post…]
On the way home from the Doctor, I chanced upon a sign outside a re-purposed Scout den just up from the road from me. I googled it, as you do “Wellers Hill Arts Hub” and discovered, to my delight, that one of the member groups was Queensland Papermakers and Artists.I contacted the president, via email, and was invited to the first meeting this year. How wonderful – a room full of talented artists, all passionate paper makers and me, someone who wants to learn how to make paper and fold the handmade sheets – huge potential. [more of this post…]
When I first saw this modular, it broke my brain, but knew I wanted to fold it. I looked and looked for instructions and finally reached out to Leong Chen Chit, through connections to Sydney Origami Group on fakebook:
Units for this model are folded from an ‘almost’ half a4 sheet, through an ingenious geometric construction you get a fan fold that can then be mutated into the basic unit. [more of this post…]
