Pack and repack articles in the same order each time. During short stays, you can then reach into your bags and find what you want without unpacking everything. Coordinate your wardrobe around a single colour; this will automatically eliminate many items of clothing
Don't pack too much. Lay out everything you'll need for the trip. Now pack half the items and return the balance to your closet. You'll still probably take lots of things you'll never get to use! If you are still not convinced, pack everything and walk around with your bags for a few minutes. If they feel too heavy, take out the unnecessary items.
Pack heavy items, such as shoes and toiletry kits, before the more delicate ones. Place them along the suitcases's spine to balance weight at the bottom. Use tissue paper to line your suitcase, and place additional tissue between each layer of clothing. Wrap it around shoe heels, and stuff it up jacket sleeves.
To reduce wrinkling, turn jackets inside out and fold them in half with tissue paper or dry-cleaning bags. Line the bottom of your suitcase with trousers, letting the legs hang over the outside edge. Then pack the rest of your travel gear, with the lighter materials on top. Wrap trouser legs over the pile; they'll keep their crease. Stuff socks and rolled-up belts into shoes to save space.
Take along plastic bags for laundry or wet swimsuits. Hang clothing in the bathroom while showering to steam out wrinkles. (Most electric gadgets can't build enough steam to smooth rumpled garments).
Bring an empty, soft bag for souvenirs. If you want to use your suitcase's restraining belts or ties, use a nightdress or socks wrapped in tissue paper to prevent crushing.
The truth is any bag lends itself to more than one method of packing that will give you well - packed luggage, whether it hangs, rolls or rides on your back.
