I use my Janome 10001 for embroidery or specialty stitches. I use my Singer 27 treadle for piecing. I use my Singer 15 electric or my Morse 672 for FMQing and my 66 treadle for most everything else. Oh, and I have an old Kenmore that I use to wind bobbins. I have an old Singer on my quilting frame. It seems that each one has a different purpose in life! Sort of like people, I guess!
