I used to just throw stuff in the suitcase at the very last minute but am getting better now that I'm traveling more frequently. Packing cubes have helped me with my organization, I don't know what I did without them. They're zippered, nylon cubes that fit into rolling luggage --- a large one for pants, middle-sized for shirts, and small for socks/underwear. I still haven't gotten to the point where I can just bring a carryon and not check a bag though...that's one of my travel goals for 2019. Hope all is well! Enjoy your trip and Merry Christmas!
