I am taking some jewelry making supplies with me on an upcoming trip, primarily spools of wire (along with the plastic doo-hicky and hook I use to knit them with). I can imagine that spools of wire might look suspicious to security personnel - I'm wondering if I should pack it in my checked luggage, or take it with me in my carry on. I don't actually need it on the plane, but I wonder if it might be easier to show and tell what it is to the security folk that way?

Thoughts (other than "don't take it")?
