Indeed, wool needles really nice. However, if you want an old-fashioned look, 100% cotton is a must. I forgot to mention in my earlier response, that it is well worth the effort to do a run of test of samples. I struggled through quilting a bed size quilt with a hard to needle bat. So, I made samples of 100% cotton, Request, Hobbs, Fairfield, Mountain Mist, as well as wool, and the 80/20 blends. I used a rectangle 6 inches x 8 inches sandwiching the batts between rectangles of muslin. On one side I hand quilted, and on the other I machine quilted. I basted around the perimeter and used a Sharpie permanent marker to write on the lower edge what it was. Then, I machine washed and dried the samples. I can't tell you how often I refer to those samples. I keep them on a ring in my studio for reference.
