I was approached by a mate mid 2018 with the idea of an original origami commission, but was given no real timeline (which for an OCD procrastinator like me is a recipe for a little crazy time.
The end result, finished near the end of February 2019, is vastly different from how I had initially envisaged it. It was actually really hard to part with this one – so much creative energy went into it’s genesis.
As part of my Pastoral Care Group “getting to know you” program, I teach my new year 5 and 7 students to fold a unit, then they teach others, spreading the skills and also helping to break down the social barriers.
We folded a nice modular, many hands make light work. In no time we had 32 modules, when locked together we have a rather lovely spheroid.
Procrastination aside, folding units for a new kusadama is always an adventure. This “parquetry” ball looks like it is made from strips of machined timbers. I decided on 3 colours, reasoning that I should be able to evenly spread the edges around the ball:
Due to the interconnections, the plan nearly worked, but the ball is lovely none the less. I really like the locking mechanism – the resultant ball is rigid and self-supporting.
As part of the Sydney Origami group’s weekly challenge, we were tasked with a modular:
This is Regenbogen, designed by Maria Vahrusheva, described in the following Youtube tutorial video
The units (you need 30 for a ball of this configuration) are quite easy to fold (I managed to teach them to my Pastoral Care group kids – their version of this fold is still a work in progress … yes, I have folded nearly 2 of these now) and luckily (for boys at least) consists of mostly folding in half – something most people can do.
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.
