I just got a Necchi 3577 from a 90 year old woman who can no longer sew. It didnt come with a manual and i can't find one online. I just need to know how to thread it on the top and know which way the bobbin should wind in the case. I would like to have it working so I can pass it onto someone who doesn't have a machine. I also got an old MW J1265 from her. Am I crazy?
