If you knit or crochet, you have at least one bin or basket like this in your house.
I happen to have about 4 of these around my workspace.
Some people might toss the small amount of spare yarn that they have at the end of a project, but I always keep mine. I'm not sure if it's a normal thing to save it, or if it's just the inner hoarder in me, but I always, or usually find a use for it! Or so I think..
