folded from 24 sheets of A9 paper (37.25mm by 52.5mm)
Finished model: approximately 9cm diameter
I noticed a mistake here.The paper size here says square,even though the actual one is A-sized.Just wanted to point that out for you.
COOL! the only thing i don't like about this model is that it's not from a square... also, i was wondering, could you make a tutorial for the three headed dragon by john montroll? i tried the other variation you were talking about with an unsatisfactory result... please repond soon! :D
