I decided to dig one of these out, to do the hem on the Yellow Peril toile for the SewAlong.
Not used it for ages, but it worked like a charm. I used a 4mm Ball Point in the Singer 611g, dropped the tension a bit, and just sewed along the pressed hem. No problems at all.
I wasn't sure if this was the right place to put this thread, so if it's in the wrong place, feel free to move it.
