Hi! I know this thread has been done before, but I cant find it when I search. I know some tPFers have a nylong Longchamp bag to cover their Birkins when they go through the x-ray machine etc. Can you give me details or point me too the right thread? Fingers crossed, I am off to see AllaboutNice in Nice next week and I want to travel in style! I'll be taking a 35 cm birkin. Thank you!
