I love my 1932 Singer 15-91 and wish that I had started using it sooner than just 2 years ago when my 1991 Singer broke a gear!!-- I use it for quilting my tops as it sews easily through the layers and often for my piecing as it is threaded and ready to go --my other machine is a fancy 1978 Kenmore!! -- if my old Singer had zigzag, it would perfect for me!!
