I had bad luck spray basting both a lap quilt and a queen sized quilt using wool batting. I read here that others have the same problem. I finished a queen sized quilt a week ago, and I will use a wool batt. I have asked a friend with a long arm to baste it for me with water soluble thread. For hand quilting, you could find someone that will baste your quilt with regular thread, using 1" stitches.
