i'm the late in life child of depression era parents so it's hard for me to just 'toss' entirely usable stuff (and that includes to an extent donating to some thrift places b/c i've seen the big dumpsters outside of them filled to bursting with items THEY purge from donations) so i'm just going to pass on some organizations/places i've found that have welcomed certain types of donations (both pre and post pandemic)-
blankets, sheets, towels-animal shelters (our local also welcome pet carriers and will post other items of need on their websites)
vhs/dvd/blurays-college and university libraries (contact to see if they have movie collections and if they are accepting-our local w/a film degree program does)
camping gear-vet (and in some regions homeless population) organizations
luggage-woman's shelter and foster care support organizations
hotel soaps, shampoos, hand lotions, sewing kits (all the stuff they restock during your stay)...-if you're like me they get tossed into the suitcase and collect over time never getting used. our local shelters gladly accept these.
books-these are harder to give away (too many donated during the pandemic) but children's books in good condition are often welcomed by school and public libraries.
household goods (some types of furniture, small appliances, housewares)-if you have a military base in proximity see if they have an 'attic'. we've always lived in proximity to airbases and found that 'airman's attics' are fairly common. these serve as a means for newly arrived service families to borrow household goods while awaiting the arrival of their own.
this one is kind of obscure but it applied to me so i'll pass it on-costumes, period clothing and accessories (c'mon-you still have an old pair of parachute pants hidden in the closet don't you?

, maybe some old boxes of a long passed family member's decades old shirts/blouses/ties/scarves). see if a local theatre group in interested. i donated boxes of old costumes and stuff i aquired from my own days of theatre. same with some furniture and (hideous) household decor-the stuff you hate to part with b/c it is so reminiscent of a certain era but has no value to sell. see if a local theatre company wants it for props/stage dressing. with kid's old halloween costumes-see if any local groups do a collection of these. we have a drive for these that starts a few months before halloween-volunteers go through them, launder and piece together full costumes for area kids.
i purged allot of stuff a few years ago but as i want to dig deeper in 2024. for me the sentimental value makes it hard for me to part with stuff but i know my adult kids don't have that connection to much of what is squirrled away. i never want my kids stuck in the same situation dh and i were-dealing with a bunch of stuff when a parent had to move into assisted living or after they passed.
