Ok, so I am getting ready to tackle my boss's reversible quilt. They want a "little weight" to it. It will be queen size using the quilt as you go method(1st time for this:\). Someone told me to use a wool blanket as the batting to provide warmth but that would not give too much weight. I recently finished a D9P that I quilted using an old quilt as the batting since it could no longer be repaired. He liked the weight of that one but not sure that I could replicate that. Any thoughts:
