Tricia, the sewing machine in my avatar is a 611g which I love. I bought it from a charity shop, and when I got it home, it would only do a straight stitch. Several weeks, and a lot of head scratching, and it showed signs of recovery, and it is now one of my favourite machines.
It does a nice chain stitch, lovely buttonholes, and can use two needles to make a twin stitch.
Thank you for giving me the opportunity to sing its praises!
Jessie
eta, glad you now have a manual for your machine.
