<insert crazy ramblings here>

Knitting needles should be fine now, though people still occasionally have trouble with the biggest sort. I've never had a problem with tiny bamboo sock needles, that don't show up on x-rays and don't look remotely threatening. Various people say that crochet needles are often still an issue, and weirdly, that the smaller ones excite more comment than the bigger ones. I store my crochet needle inside an empty Muji pen with my other pens when flying.
