Sometimes customers ask me to put more than one crane in a jar so I have to fold them even smaller, around 7.5 mm too. I think anything smaller than that is too hard to see and the paper doesn't hold the folds very well unless you use good quality foil.
Thanks for the comments ^_^ The folding part wasn't as challenging as setting it right inside the jar, I usually squish like 4 cranes or more before getting one to sit right LOL

my friends just gave me
like, 5 REALLY SMALL
cranes! : i think imma
