Since Marie Kondo’s tidying up method is all about objects that spark joy and nothing sparks joy like taking a vacation, what does the organization expert have to say when it comes to packing a suitcase? In a video she shot for the site Apartment Therapy, Kondo details the steps you should take to maximize the most space inside your carry on. Folding properly is an important detail, making sure to get your clothing as small as possible. Tucking articles into others will free up room as well. Kondo also recommends using bags to keep similar items together like charge cords and shoes. Of course, the KonMari method is in full effect, with the expert advising to use her “spark joy” test before placing anything inside the suitcase.
