I have found my charities that I quilt for thru a church group and a local quilter's guild. If you are in Southern CA, I would contact a LQS called the Calico House located in Yorba Linda CA. They are a Gammill dealership so they quilt lots of charity quilts letting new students practice on those quilts. They probably could refer you to a local charities. One of my friends sent me this information.....
