I flew last year with a set of 4 double pointed knitting needles with the sox I was making. Never a question. But when we got to Australia ( the land of wool, right?) there were signs that knitting needles were not allowed. Makes sense. You could do someone a damage with knitting needles. So it is a toss up. TSA is one of the great examples of "Chicken Little" we have developed since 9/11. I like the idea of carrying a printed copy of the regs in country. If you go overseas, all bets are off!
