Yesterday, while reading a manual for Singer Golden Touch and Sew on Singerco.com, I read that machine can do chain stitching, but you need a special bobbin cover, a little round plate that fits over the bobbin, under the plate. It isolates the bobbin from the needle. Says it will ravel readily and should be fastened with a sewing needle at the ends of a seam. I was flabbergasted, for lack of a better word. It was a model 750. Wondering if Cathy has seen one of those little plates floating around. I would like to try it. I have the machine temporarily.
