Why not contact a guild near you (or if you don't know of one, ask at your local quilt shop) and offer to bring a few boxes or bags full for members to make charity quilts?
Our local adult day center has ongoing craft events. If there's one in your town, they may be happy to have some.
We regularly have a clothing giveaway in our community, and besides taking old clothes, the folks there have a rag pick up. Contact your local solid waste management people.
Good luck!
