I folded the scaled koi from lang
First i made a 11x11 (121) scaled pattern: (out of a 50cm x 50cm sheet)
Then i had to increase the pattern up to 13x13 scales (169), because the scales didn't cover the whole body
Then the hardest part: the scales
And finally i have a nice scaled koi out of foil paper: the model assumes a permanent form
Hope you like it
