I had a friend do this , she brought a very thick batting , look lovely a puffy she then took it to her Long Arm Quilter and had it channel quilted , then set about making the cover it was like doing quilt as you go , yes it took some time but she was working without a pattern or any idea how to go about it , but it did turn out lovely , I would have been happy to drape it over my bed , funny thing she didn't want to share . Good luck Cathy
