For me and my family circle, I would not think it rude to knit, bind or quilt, crochet or embroider after the formal part of the gathering is over, that is, eating together at the table. I do think it would be rude to sew at the table while others are eating, not to mention the risk of getting gravy on my quilt! (lol!) For me, doing handwork is easy to pause to look at the talker or to make a comment myself, still being present to the small group chatting while others watch the games. I love being with my kids and grands, whatever we do.
