Over the years Singer and other manufaturers invented and marketed a lot of accessories. You can buy zig-zaggers, one step buttonholers, wide angle & narrow hemmers, 1/4" feet, blind stitchers & an amazing array of additions. I haven't even begun to play with all my accessories.
They are cute, compact, tidy and fit in a box 13 x 10 x 8. The whole package weighs less then my more modern machines. I do like my needle down and other fancy features, but the FW's have their place, too.
