Bedspreads, sheets, and towels can be donated to shelters and vet offices. It doesn't matter if they are stained or not. They also like diabetic supplies. My mother is always changing what she uses for her diabetic check and she donates the thing that pricks you and registers your blood sugar levels. Sorry I do not know the name but they do use the ones she donates for some reason.
My kids love making bowling pins out of the creamer bottles. They put sand in them and paint them and roll balls at them etc.
