Yes. I do name my machines. I started doing this when I was given a machine that was well loved by her previous owner who passed away. I named the machine after her and then I continued the practice.
2001 Singer machine I named Vesta , because I like the name.
Bernina 1530 named Martha, after previous owner.
Singer 15 hand crank named Black Beauty.
Brother PE770 Embroidery Machine named Myrna, named by my daughter who gave it to me.
Janome Horizon 7700 named Magnolia, because she's all white.
Singer Featherweight named Katie, because I like the name.
Singer One named Bronwyn, because I like the name.
I also name my automobiles.
