I heard recently that our local Goodwill thrift stores had started a 'bit wall' with all sorts of little sets of bits. This was important because I heard it from a fellow gamer, and we were talking about game bits, which are always needed, and I like to craft with them sometimes, too.
The 'bits' I found this time, was thread. Awesome sets of three-to-a-package DMC thread, on their cards, with their numbers written on already. I got four. Aren't they beautiful!?!
