Yes, I do name my machines. My best friend is "Sunshine" (Bernina230). My Bernina serger is "Ben" (short for benevolence, as the machine was practically given to me). My Mercury industrial, who has a big "M" on the end cap, is "Max." My Singer treadle is "Grandmother." She belonged to my Great Grandmother, who insisted on being called "Grandmother" instead of "Grandma." The old metal Kenmores that I rescue and give away are "Kenny" and "Nellie." My 60 pound Kenmore is "Carol," named after her previous owner.
I still need to name my old 930 Bernina and my HandiQuilter.
