Some Dennis’, some mine, some both:
TRYING TO QUIT (maybe building tds will keep us out of Barnes & Noble):
Books (not exactly useless, but definitely an obsession - we‘ve tried to get it under control by agreeing that for every book we bring home now, we have to get rid of TWO until everything fits nicely in the shelves in EVERY room. It at least makes us stop & think, which two are we willing to part with)
Magazines (as was stated by someone earlier, can’t throw them out…)
SOMETHING SMALLER, MORE MANAGEABLE:
Post cards
State magnets
Pictures of vintage trailers
Knives
Water towers and welcome signs (that is, we photograph them in our journeys)
Jigsaw puzzles
IN THE PAST (have these collections but have stopped collecting and just kept a few favs)
Steins
Angels
Eagles
Miniatures
Milk crates
