I belong to a church knitting group (we also crochet and sew). I pick up my granddaughters from school and I always have something in the car to work on while waiting. I bring work in cars (ask the driver if they mind), planes, trains, anywhere I can pick up a needle or hook. Contrary to what most people think, you can bring knitting needles (and crochet hooks)on planes (scissors are a different problem); I have a pendant which I wear with a small stationary cutter inside. Go to www.tsa.org for their list of prohibited and permitted items.
