I have used Hobbs Wool Batting. Several years ago I had bought a roll of it. It quilts and drapes beautifully. My quilts are machine washed and dried. There is some shrinkage. My only problem with it is the loft. I machine quilt on my domestic sewing machine. The Hobbs wool has more loft than the Hobbs Hierloom 80/20 cotton/polyester. I had to pin baste much closer together on the wool to prevent puckers because the batting is puffy.
