Good question. I have an Baby Lock Ellisimom, a Singer Quantum CL, a Baby Lock Serger and my old Baby Lock Ellegante (that I am trying to sell). I use to just sew with my singer, then I sewed with my baby lock and really liked it, so started sewing with it and the singer sat. Now I have learned that you must use your machines, they are like cars and must be "started up". For classes I use to take my ellegante. I had one doing embroidery while I sewed on the other. In the end I have decided I have "too" much and need to get back to basics. Not much help, am I?
