I think after all the fussing you will do , trying to figure what you can take, is not worth it. Just put everything in your checked luggage. If you are just doing carry on, leave everything quilting related at home. Trust me , you probably won't even pull it out when your in your seat. Just take a good book and relax. How much can you really expect to get done. Even when you get to your hotel, you will be tried from site-seeing, and all your adventures. Enjoy your trip.
