In less developed countries, the odds get worse. If you have an extremely compatible traveling partner, you might consider packing half of each person's things in the other's bag. Although perhaps more relevant to business than vacation travel, most of us do not want to spend our days looking like a wrinkled mess. By pristine, I mean that garments will have creases where we want them to be, and not have creases where we don't want them. The way in which the clothing is folded for packing, however, will play a considerable role in the outcome.
Creases come from applying pressure to hard folds .
If you wrap a piece of paper around a cylinder, it will be easy to straighten again. If you make a hard fold in the paper, it will be more difficult. If you apply pressure along the hard fold, the crease will be even more pronounced. Clothing is no different. Bundle folding involves the careful wrapping of clothes around a central core object, avoiding the hard folds that result in creases.
