so far DH and I only have one machine that is named - he calls his Pfaff 130 Brunhilde, because she's such a heavy, stout girl.
I'm not into naming things much, maybe I will when I get them staged = give them all a plaque with a name and mfg info. Might be fun to do.
I figure even if I gave them names I'd still have to refer to them by make/model as no one else is going to know what I'm talking about if I called them by name.
