They update the rules (daily it seems!) often, but I ALWAYS took sewing needles. I just tucked them into my change purse where they hung out with the pennies! Domestic rules say scissors with less than 4 inch blade> that included a pair of scissors I LOVE that I found at the dollar store. I had forgotten them in the bottom of a bad. They were measured and handed back. I was SHOCKED. They are the regular sized like Fiskars. In pinch I have used nail clippers..which you CAN have. My problem sewing when I fly is no elbow room. I have trouble hand sewing with my elbows tucked in at my side!
