Once in the garment bag, if you can, leave it hanging up during the course of travel. If you can’t leave it hanging, lay the bag folded lightly in half with nothing on top of it.
If you are packing the clothes for a move, consider boxes over bags.
Once you have them unpacked, hang linen clothes up. If there are wrinkles, you can hang them in a bathroom and turn the shower on hot for long enough to make the room steamy. You can gently pull at the linen to help release the wrinkles. It’s also a helpful option to pack wrinkle-release spray when you anticipate possible wrinkles. You can use a steamer or blow dryer to release wrinkles. If you have an iron or steamer available, this is a good option for immediately removing wrinkles upon unpacking. Another good option is to spray the linen item with water, especially in the most wrinkled spots, and then turn the blow dryer on the clothing. The heat will help release the wrinkles.
When you fold the clothes, there is still a chance of wrinkling. One trick that might help is to put a little extra tissue paper along the parts of the garment that are folded. Giving the folds extra padding can help keep from forming hard creases.
If you are packing for flight, consider placing linen clothes in the middle, as baggage workers may not load and unload bags with the top up. Placing them in the middle ensures that if a bag is flipped upside down, all of the weight won’t end up on the linen.
Fold pants in half lengthwise preserving the crease in the front of the pants. Hold the pants at the hem and slowly roll all the way up to the waist. Gently smooth the pants along the way to reduce any extra creases forming.
Place lined linen on top of all other clothing.
This helps the linen clothes by letting them form lighter creases than if they were folded up tight.
