Quilter's Dream has a program for charity quilts. Why don't you give them a call?
From their website:
"For charity groups we sell what we call our “Seconds” in Quilters Dream Batting, when available, at a large discount. Our Seconds are a wonderful value, as they are still a great product with never any holes or major problems that would prevent them from making a nice quilt. Our charity groups absolutely love them. If you would be interested in these Seconds, please give us a call and we can let you know what is available. (The types and quantities of our Seconds are constantly changing)."
