Origami Hydrangea HydRingEa Tessellation – When I started my journey into the land of the Origami Hydrangea Tessellation (Design: Shuzo Fujimoto), I came across an interesting design that makes use of the original Hydrangea flower tessellation, but arranges it in a circle with other tessellations. This wonderful model is called HydRingEa Tessellation and was designed by Robin Scholz. But don’t be fooled by it’s beauty, it is an advanced model that might not be suitable for everybody. Robin Scholz was so kind to make instructions and CP for the HydRingEa Tessellation available for everyone to download. You can find it here.
Paper For HydRingEa Tessellation
You can use a variety of papers for this model, starting from regular Kami, to Kraft and Tant. You could also try this model on transparent paper like Glassine to get this added WOW effect when backlit or held against the window. You should aim for a paper that is strong, yet flexible enough to withstand the pre-creasing and the following folding. I was looking around for quite some time and even bought and test folded (the Hydrangea) a few different papers until I decided to go with Kami. The Hydrangea tessellation is the most demanding fold that needs the right kind of paper. If you choose wrong, you might not be able to fold the Hydrangea design to your satisfaction. Some papers are nice and stiff, yet not bendable enough when you want to reverse the folds for they Hydrangea, and your paper might tear or make a new, unwanted crease.
You should know that your finished Hydringea tessellation will only be about half the size of your original starting paper. I test folded the pre-crease pattern around five times with different sizes and kinds of paper. In the end, I decided to go with 60 cm x 60 cm / 24 in x 24 in paper. It was probably not the easiest size to start with, as it spread to almost the whole width of my table, but was the right choice in regard to the Hydrangea tessellation folding. You probably could fold a mini HydRingEa Tessellation with 35 cm / 14 in paper. But don’t expect to add many levels to your Hydrangea if you go with this small size. Also I think a little error in your pre-crease stage will show much more on the smaller scale than on the bigger.
This model is folded from a Dodecagon – the instructions (last page) show you a way how to get from a square sheet to the dodecagon.
Testfolding The HydRingEa Tessellation
I would recommend you test fold the pre-crease pattern at least once, so you get a feel for it – before you use your actual project paper. You should definitely get familiar with the Hexagon Double Pleat Collapse on your test model. I even folded two more test models of a Hexagon triangle grid to test the collapse of exactly this step. You then get a feel for which folds have to bend in which direction, when attempting the actual Hexagon Collapse. The instructions to the Hydringea tessellation also provide some pictures to solve this problem in a different way. You should see which fits you best.
You should also test fold the Hydrangea (as mentioned above) on your paper, to see how it behaves with your paper. In general, it amazes me each time when I fold this design, that the paper gets more and more elastic and easier to handle with each level you add.
As one of my last steps, I used my two Hexagon test folds to try different ending designs for the middle feature.
If you read in between the lines up to here, you will have realised, that the Hydringea Tessellation is no quick nor easy Origami model. You should split this project into several steps – as each of them might take a few hours. I think you can divide it into 5 stages: Pre-creasing, Hexagonal Double Pleat Collapse, Collapsing of the Hydrangeas and the Double Triangle Pleats, Folding of the Hydrangea up to the desired level (or what your paper size permits), finishing of the model with the centre feature and the remaining decorative folds.
HydRingEa Tessellation Conclusion
I think the Hydringea tessellation is the most appropriate model to conclude my journey into the Hydrangea tessellation. You will need to have proper knowledge of the Hydrangea folding and some kind of tessellation experience. The instructions provide step by step diagrams of the whole pre-creasing requirement. The collapse of the Hexagon centre is described, but might not be enough for everybody. From this point on out, you are on your own – so you should know by yourself how to collapse and fold the Hydrangea and the Double Triangle Pleats.
