Well, after several delays -- and some plain old laziness -- I finally finished the Cary Grant pattern. Other than his cleft chin (Groucho had his mustache, glasses, and cigar; Bette Davis had her "eyes"), he doesn't have any physical characteristics that stand out. So I'm not sure how good a likeness this is. I mean it's kind of hard to capture his charm, elegance, sophistication and accent in knit, I guess.
Anyway, here he is.
