There are RSVP (retired senior volunteer program) offices around the country. If they aren't interested----my local ones would be ecstatic!! Library sewing groups will enjoy the chance to shop for free (and extras may even benefit your local library in sales). There are other organizations that provide materials for their volunteers. Some hospice organizations will even send someone out to your home to pick them up. If nothing local works for you, freecycle is the next best bet. If you are uncomfortable with people coming to your home, you can always list the neighbor's home {with their permission} and state they'll be on the front porch.
I've had great luck with all of these methods.
Best Wishes,
Heather
