Knit small, knit large

Buffy, you've answered the question.

But I've got to say that the big sleeve had a certain something!

I know you've positioned it "just right" for the photos, but in my mind's eye, I see it flowing and blowing and waving about. I just go back to the traditional Chinese holiday costumes, so huge and undulating with movement. But then those were used in ritualized dancing so there was motion most of the time

Smaller sleeves are more practical. I've heard you must reach the great age of eighty before you can begin to be impractical.  We're not there yet.
