I have only used Quilter's Dream wool batting. One of the quilts, which I have been hand quilting over a period of time, has black on the front, and the batting is bearding through. The other quilt I washed and dried in the dryer, and it came out fine (was light colored fabrics on top with a white backing). Next time I try wool, it will be Hobbs. I really love the Hobbs Tuscany wool-cotton blend; it's my favorite batting so far. It is very soft and cushy and seemed quite lightweight to me.
