The bride and I are not very close. I wouldn't recognize the groom in a line up. (I know the first two facts have no bearing on the answer) Her wedding is in a park. May I bring my knitting (probably the blue lace scarf, perhaps a purple sachet) and work quietly at it before the procession begins if I find myself bereft of conversation?
We are already bringing the gift to the reception, which makes my skin crawl. I would rather not commit two faux pas in one evening.
i don't think it matters how close you are, you can't knit during the wedding. most ceremonies are under a half an hour anyway so what's the biggie? sure it's probably gonna be boring but you just gotta suck it up.
also- it's not a faux pas to bring the gift to the reception. that's how most people are doing it these days. you'll probably see a big table of them when you get there.
