From the original Hydrangea Tessellation, designed by Shuzo Fujimoto, others have invented new Origami models, that use this design, for example this Origami Hydrangea Tessellation Box! With only some minor modification you can transform the finished tessellated work into a lid that will fit a regular Masu box. I don’t know the author of this design. If you want to fold a different Hydrangea project that uses the same basic tessellation as a starting point, check out the Hydrangea Cube.
Hydrangea Tessellation Box Folds
First you need to fold your Hydrangea into as many levels as you wish. I used regular Kami for both the top & bottom of the box. I managed to fold 8 levels from a 20 cm / 7.8 in square paper. Then you open up the out-most (largest) layer and shape corners that will be petals as well. The finished lid measures 5 cm x 5 cm x 2.5 cm / 2 in x 2 in x 1 in. Now you just need to fold a simple Masu Box (divide by 3) and put it together.
Besides the regular size box Hydrangea Tessellation Box, I also played around and folded a 4 level Miniature Hydrangea Tessellation Box. As a starting paper I used Japanese Harmony paper, which measured 7.5 cm / 3 in. The finished lid measures 1.8 cm x 1.8 cm x 0.9 cm / 0.7 in x 0.7 in x 0.3 in.
