I’ve always been a fan of origami koi. There are only a few major koi designs but they’re always great and the koi people fold are always really beautiful. Often people use really great paper or make collections of rainbow coloured koi and do lots of other neat things with them.

Our first image is this beautiful collection of rainbow koi.

Lots of people have coloured their paper so their koi look very much like the ones in real life.

This koi is pretty neat because if you look closely you’ll see that the colouring is in the shape of Japan.
