I thought most of the tricks unhelpful.
Packing by days: you’ll take way too much clothing as you don’t rewear any clothes. Packing a wardrobe instead of outfits creates versatility with fewer pieces.
Using plastic wrap to store necklaces: only good for a single use. I’ve found that storing a necklace in a pill baggie works well, especially if you close the necklace before storing. Also use one pill bag per pair of earrings. Then put your baggies into a small zippered bag. They won’t tangle but are still together so you can’t lose them.
Money everywhere: lots of work to hide it, and most likely you’ll forget what you did with it. I can easily see some of it falling out on the floor when you access the storage item. Certainly store some hidden away, but do it where it can’t fall out. A pocket in a toiletry kit, hiding some in the luggage lining works better. And put it in a zip lock to keep it protected.
You also can’t store liquids in your shoes if you are flying by air.
So many of these hacks are a lot of work with a very low payoff.
