For a few weeks I have this great model, the Hearty Cube by Meenakshi Mukerji, on my Origami to-do-list. Finally I found time and enjoyed folding and assembling this cute model. By the way, you can find the diagram in Meenakshi Mukerji’s book “Exquisite Modular Origami“, p. 10. There is another Origami Heart Cube, by Fumiaki Shingu,which you could try to fold as well. The diagram can be found here and it is available for free. It is not exactly the same design, but still very nice as well.

Paper & Measurement

For this Hearty Cube you should have Kami or Duo Colored Origami paper at hand. A great contrast in color will bring your cube to life. But you could also fold it with any other paper, if you don’t happen to have Origami paper (e.g. colored notes paper comes to mind). I have folded this model with very thin Kami paper & slightly stronger Kami paper, and both finished cubes hold their shape nicely. I used 7.5 cm x 15 cm / 3 in x 6 in large paper.

Fold the Hearty Cube from Japanese Kami paper or give it even more color with Duo Paper!


The folding of this model is very easy. There might be a slight inaccuracy when you try to shape the top part of the heart. You will know what I mean when you reach this stage. You can try to pull with one hand the paper apart and with the other hand push the triangle fold down. In any case, even a slight inaccuracy will not be visible once the cube is assembled.

The Origami Hearty Cube by Meenakshi Mukerji can be assembled in a formation of 6 or 24 modules. This reminds me a bit of the Sonobe Cube Tutorial, which I prepared last year. You should definitely check it out, if you happen to like modular Origami cubes.

6 Module Cube

When you fold the 6 module version you will need to crease both sides of the cube front. The finished cube will show two tri-colored corners, both on opposite sides. Other assemblies are possible as well.

24 Module Cube

When you try to fold the 24 unit model, you will only need to crease one side. There are two main ways in which you can assemble the 24 module cube: Version 1, colored corners or Version 2, where the 4 colored centers are on each face the cube . Each of these assemblies needs a different crease at the very end (Step 10 of the diagram from The Fold Magazine). The colored corner formation only needs to have the left side of Step 10 of the diagram creased; and the colored center of the cube front version only needs to have the right side of the cube of Step 10 of the diagram creased. The version, where the 4 colors show up on each cube face seems to be slightly sturdier, as all ends are properly woven into each other. The assembly for both versions is slightly tricky, as you will need to balance and weave the modules into each other. It is probably best if you don’t drink too much coffee beforehand, so your hands are more steady. 😉 I used the help of the table (to steady the work) and two toothpicks to open (and hold open) pockets.

I am sure most of you will manage and enjoy this model very much. You could probably try to fold this model from tracing paper and use it as a lamp. A measurement of 20 cm x 10 cm / 4 in x 8 in would be the right size as the starting paper, I assume. By the way, if you want to fold another interesting modular Origami cube, look at this model, the Hydrangea cube.
