My first thought was for shelters - either human or animal. Then I remembered the old play quilt that I had growing up. My mom kept this quilt in the car to wrap up antique furniture she purchased for her shop. But when we were home, I was allowed to use it in my yard for picnics with my dolls or if the boys were outside, we would play cars on it. She doesn't purchase antique much anymore but she still keeps an old quilt in her car.
So you could maybe give it to a teacher for outdoor reading time or to a parent for a child's playtime.
