I like Quilter's Dream battings, too. I like the next-to-the-thinnest for machine quilting. I think it is called Select. You can order even just one batt and they will ship it to you, so you don't have to store tons of batting. Another batt which is thin and is supposed to hand needle wonderfully is Thermore. It is a thin polyester which is very flat and a very even thickness. I have used it on a machine quilted quilt. It was so easy to work with.
