I think there should be a #littlelibrary in every laundry room, or place where people have to spend idle hours, in the world.
One sure isn't enough!
I was surprised at how much it's used, and how many people really enjoy it. I'm sure if you can find a place to put one, you'll be happily surprised too.
There are also #littlepantries, where people leaved canned food and things like that for others who need it to have for free. You could also make a #littlecloset with free clothes, or any other kind of thing people might need.
Definitely, one isn't enough. I've taken note of the additional ideas you've shared, thank you so much.
