I got really intrigued when I saw the Origami High Density Hydrangea Tessellation on the IG a few days ago. This really sparked a renewed interest in the Origami Hydrangea folding. You should have a look my last article, where I compared several papers (Kami and non traditional Origami papers) on their suitability for the Hydrangea tessellation. It is actually quite important to choose the right kind of paper for your Hydrangea folding, as it could mean success or failure. The High Density Hydrangea Tessellation is designed by Shuzo Fujimoto & Peter Budai. The diagram for the original Hydrangea tessellation can be found in this book!
3 x 3 Tiles, 5 Levels, Finished size: 8.5 cm x 8.5 cm / 3.3 in x 3.3 in
In this particular High Density Hydrangea tessellation, I combined 9 Hydrangeas tiles (in a 3×3 grid) and it is called a High Density Hydrangea Tessellation. You can basically make this in any kind of constellation. I folded mine from one sheet of Kami with the measurements of 20 cm x 20 cm / 7.8 in x 7.8 in. I chose this small size on purpose, as I wanted to fold a Miniature High Density Hydrangea Tessellation. This is super small if you need to fold 9 separate Hydrangeas out of it. So it is probably best, if you try with a bit larger paper, as it just isn’t much pleasure to fold that small. You could probably aim for paper the size of 35 cm x 35 cm / 13.7 in x 13.7 in.
If you are interested in folding the one I made, you should look at the crease pattern I drew for the High Density Hydrangea Tessellation:
You basically start with a 10 x 10 grid. As there is no easy Origami way to divide a paper into 10, you will need to measure and mark with a ruler. Once you have this grid, you need to mark the half way lines that are reoccurring in batches of 3. After you folded and creased all vertical and horizontal lines, it is time to turn over your paper and start folding the diagonal lines. Check closely with the CP, so you get all lines correctly.
The next step after you have all creases on your paper, is the collapse of your paper. It is best to fold the basic model (one Hydrangea) first and see how to collapse it. Then after you are pretty confident, you can try to collapse 9 Hydrangeas at the same time. Take time for this step and slowly make your way around the paper until you can collapse the sheet in one go. If you used Tant, then this step would be easier than if you used Kami, as Kami is much softer. For the purpose of taking pictures of this process, I creased a second 15 cm x 15 cm / 5.9 in x 5.9 in sheet of Tant.
Folding Of High Density Hydrangea Tessellation
Once your paper is flat in front of you, you can begin to fold the basic model over and over. This should not be too difficult if you have some experience with the regular Hydrangea tessellation folding. Again, it depends on the size and type of the paper, as to how many levels you will be able to fold. I managed to fold 5 levels with my 20 cm x 20 cm / 7.8 in x 7.8 in starting paper – but I have to admit, that it was not much pleasure after probably the 2nd or 3rd level. From that point on you, can only fold with tweezers and toothpick. And at a certain point you just want to be finished. 😉 For comparison, the 5th level petals were only 0.4 cm x 0.7 cm / 0.15 in x 0.27 in small.
I hope I have somehow inspired you to fold your own High Density Hydrangea Tessellation!
