I've never named a quilt but I did have a car I called Ethel. . As I too have an Opal 670 maybe I'll call it opal it only seems appropriate. I like the concept of naming a quilt but often I don't "get it" when I see other people's chosen names so I just haven't bothered. I've also never labeled a quilt but I've only completed 4 so I hope I'll have lots of opportunity to decide whether to start naming or labelling.
