Origami ‘Bipyramid’ Tutorial & What To Do With Them

The shape of this geometric origami is called ‘Triangular Bipyramid’. I know, a bit tricky for kids, but the origami itself is the easiest to make and has many fun uses.
To remember this name is actually straight forward. Bipyramid means two pyramid shapes mirrored back to back, and this pyramid has triangular sides, so there you go.

Here’s how:

Cut a strip of paper with an even width. The width and length should be at least 1:4 or 1:6.
I just cut a rough length that looks long enough and adjust the final length as I make it.
Fold a small triangle on one end.

Fold backward at the end of the triangle and repeat fold like an accordion.

Fold the straight lines between the diagonals again to change the fold direction.

You can string them easily by taking out the last triangular piece, placing a string through and closing it up again. Or use a big needle and thread.

  1. Help! I’m stuck after the accordion, I think I’m overcomplicating this… haha I keep ending up with a 6 sided shape!

    • Hi Andrea, I think you’re doing it correctly, because it is a 6 sided shape! This triangular pyramid has 3 faces on each side. Maybe it looks simpler than you imagined! Hope you enjoy them : )

  2. These are also known as crane eggs, and you can even buy paper specially made for folding them!

  3. So adorable! I’m making these now. How did you keep the triangles suspended on the string for the mobile without having them all slip down to the end of the string? Thanks!

    • Thanks Jane! When I made them some slipped down but most didn’t so I just left them as they were. (I used a slightly chunky thread.) But I think you could just make a knot after the shape, or use tape inside the flap (the last bit) which won’t show when you close them up. Enjoy!

  4. so, cool, I will put treats in them and use them as a fun start to our Ancient Egyptian home school study unit and they can make the necklaces. I love your ideas.
