I'll chime in. Yes I have named all of my machines. I tend to use alliteration so I can remember what they are.
My old Kenmore was Kandy, but I don't have her any more.
Miss Ida a Singer 15-88 treadle; Florie a Singer Red Eye treadle; Fessie Mae a White Rotary; Sylvia a Singer Red Eye electric; Boris an all black Singer 66; Hugo a Singer 66-16; Thelma Singer 301; Freddi a Singer Feather Weight; Freda a PFaff 3.0 Expressions; Tracky a Singer I bought at a tractor show; Fussie a Singer 15-91 can be temperamental; and Opal a Singer 252; and Wilma a Wards Signature.
I like to name them. My family really thinks that's nuts and makes fun of my talking about my machines, but hey they are my ladies and gentlemen. We get along fine in our part of the world.
