Your scissors and rotary cutter can go in your checked luggage. If you have a standard size sewing machine you can carry it on - although I will warn you that as it goes through the x-ray machine the TSA agent with say "what is this?" They do not see too many sewing machines. They may ask you to open it - but then it will be fine. I took mine on a long business trip with me in 2008. It was fine. I have a Husqvarna Viking Rose, which isn't too big. I did buy wheeled travel luggage for it - don't try to carry it - must have wheels.
