I name them because they are my "art". Last month my BIL and SIL were here and looking at a top I had just completed for their daughter for graduation. They asked, "Does it have a name? Are you making a label like the others?"
I told them I was considering it and they told me I "had" to because everyone loved that part. They like seeing the name and figuring out why I gave it that name. My labels have the quilt name, for , by Mary, occasion, year.
Btw, our cars have names including the trucks. My favorite name is Uncle Jesse. It is a 1968 F150. My kids thought it looked just like Uncle Jesse's on Dukes of Hazard.
