paper handicarft - Box (Triangular Bipyramid)

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.
