I am having a senior moment, and for the life of me I can't remember how I wound the bobbin on my tredle machine last time!! Yes I know old age or cold weather or something.
It's a long bobbin called fusée here in france. I have put a couple of pictures up on my personal pages. Just click reedle machine on the link below.
Links to a page explaining it would be helpful or your personal knowledge even better. Thank You Claire
