Packing a week’s worth of clothes into a mere carry-on? Yep, it can be done. Start by packing on your bed first—laying everything out will help you see what you really don’t need to bring along. Roll up jeans, sweaters, pajamas and anything else that won’t wrinkle. Fold your winkle-prone clothes in tissue paper and put them on the top. Be sure to stick socks, belts and anything else that’ll fit into the shoes you’re bringing. And always find a way to fill every available nook and cranny, naturally.
