I agree with the others - you can never have too many machines! I have 2 older Kenmore machines I would never sell. I have an Elna serger, Janome MC4800 and Compulock serger, was given an older Singer in a cabinet. I also have 3 Singers I used to teach sewing classes. I bought an extra Janome serger for class -- then -- I bought a Janome 11000 mainly for my embroidery, Janome 1600P for my Hinterberg quilting frame and a Janome CoverPro1000. Looks like 13 for me! I also have an Elna machine that needs work, an antique treadle machine, a Singer in a cabinet in the shed and a Kenmore that I canabalized when I fixed another machine and an old Singer in a portable case - oops - that's 18. Whew!
Sewing Machine Owners Anonymous - where's the first meeting going to be? I need to sign up!
Now, if I can just find the time I need to sew and quilt!
