My Janome 6500 is Diamond Lil because it was expensive.
My Janome Platinum is Baby Jane since it's not a full sized machine.
My featherweight is Miss Lizzie since she was made in Elizabethtown NJ and also because my grandmom's first name and my mother's middle name was Elizabeth.

My Bernina 830 was purchased with an inheritance from my father and I named him after my dad. His name is Welty.

Not too original - my Janome is Jan. Don't think I ever named the FW, but she is my Little Sweetie.

I only have one machine, a Janome 6600 who so far has done everything I've asked of her. I haven't named her yet, but there are days when a nasty name is uttered....usually when I've done something really stupid and try to blame the machine....LOL. In all honesty, I am usually too focused on what I am doing to worry about names.

My bernina's name is Bernice Rose. Bernice is Bernina and Eunice, my mother's name , and Rose is for my Viking machine I used for a trade in.

"Sir Chugs-a-Lot"

My Bernina 1080 is just called "my Bernina". But when my 16 year-old daughter was a little girl, "Bernina" was always the name she would call herself when she played dress-up or did any kind of imaginative play. For years she would don a different personality, brandish a British accent (where she got that I don't know) and approach me with a "Hello, dahling. I haven't seen you in evah so long. You remember me of course -- I'm your dearest friend in the world, Bernina!" I guess it is a pretty name for a girl. I sometimes wonder if she'll one day name a daughter of her own Bernina. I hope so. (Also, for the above reason, I'm glad I don't own a Pfaff!)

I named my Pfaff Pfanny...

I've only named the Singer that was made in Scotland. She is "Lassie", of course!

Bernina is Bernie, lightweight is Itsy
