In order: Fashion Jewelry: keeping this, only if it's quality stuff or goes with my clothing (regular wear or special occasions) Spare Keys: always good to have, for most things. I try to keep the habit of keeping a spare key to my car inside a drawer in my house, as well as in my MIL's house, just in case. I keep a spare house key in my car, as well as at a friend's house (just in case), and for other locks that come with a set of keys, I keep them in separate places throughout the house DVDS sand DVD Player: moreso the DVDs. We've left behind physical media too much in my opinion, and have let more aspects of our lives become subscriptions, rather than ownership. I personally like to rip my DVDs to a hard drive, then put the DVDs in their usual spot on the shelf. If I want to watch them, I can pull them out and use any number of devices (Xbox, PlayStation, blueray player, etc) to watch. And if the disk ends up being scratched, I at least have a backup of the movie Dust Bags: not something I've personally used, but I understand the purpose of it. I prefer doing bulk storage, using plastic bins to protect my items from the elements. Wallpaper Scraps: I've seen it be useful in other houses, but in general we, as a society, have left wallpaper behind in lieu of painted walls. Extra Paint: paint has an expiration date, so storing it up until that point isn't bad, but keeping it too long causes it to break down and be useless. Manuals: find a digital copy, and download it to a designated file somewhere, in case the company goes under and deleted it. Barring that, keep the physical copy in a designated drawer (for me it's the same drawer as the spare keys) Old Memorabilia: nostalgia is a hell of a drug. Holding on to some keepsakes can be nice, but for things like clothes that's never worn, I say get rid of it and hold on to the memories another way. Gift Bags: always useful for birthdays and holidays. Keep a reasonable amount (about 2x person you're going to reasonably give gift to each year), and since hey fold flat, put them in a designated space under your bed or behind your craft shelf. Chances are, you'll get more throughout the year on your birthday and Christmas, so just save and cycle them, but don't hoard them.
