Hey, thanks !
Looks like this :
US size + 1,
metric size + 5
Nice to know.
AFAIK, metric 140 is the max size my machine should be able to handle.
So as soon as I find a french supplier for size 140 needles, I will order nylon thread and fabrics from a US supplier.
Thanks a lot, Ken !!
You are a wizz for Internet searching !!!
