I have a Singer 101 that I inherited from my mother and grandmother. I use it for upholstery, pool covers, curtains and the like. I love the machine; nothing fancy but what a nice stitch! The best thing about it is the gear drive (no belt) will sew through just about anything. I think the cabinet is one of the nicest made. It takes any low shank attachment, which gives it zig-zag and other capabilities.
