I was at a Tractor show and purchased a Singer Fashion Mate sewing machine. It was really cheap, but I thought I could use it for workshops and leave my $$$ one at home. It is a portable and light. The seller had lost the manual with it. Said she sold it because she just doesn't use it. It runs, but I am having difficulty with the thread tension. I am also not sure which bobbin is correct. Does anyone have any ideas or knowlege of this brand?
