I think they're slightly different skills. I'll fiddle with a sleeve, doing some easing and making do (mind you, more of a costume maker than a true seamstress - I was the family "make the choir blouse for your sister", "figure out this dance pattern for the other sister", "can you turn this into something Hallowe-en-ish?"). The precision of quilting belongs to my precise sister, in a direct line from my precise father. If she says, 25 mm she means that, and not a fraction more or less. She's a little frightening.
