Yes, all the eyelets were done by hand.
First, I punched a hole with a big sewing needle, then with a small knitting needle (size 3) and finally with a big knitting needle. I guess there is a special tool that does all that stuff but I dont have any and didnt want to buy one.
The sewing part is similar as a circular button hole (it maybe not historical accurate but it worked fine).
Quite easy. But also time consuming
