When i flew to Mexico about two years ago i was able to bring very small gauge circular knitting needles and two crochet hooks (metal) in hand carry from the US but had to check them from Puerto Vallarta. Online sources seem to indicate that DUB requires checking them. The crochet hooks i had with me had been my grandmother's so i went back to the counter to check them with my bag. I would recommend against bringing needles that she's fond of just in case. Bamboo needles seem to be less of an issue but still may be disallowed. The inconsistency is a pain in the rear.
