What I used was wool from the inside of an old quilt. Most likely it had never been washed, as we would take the quilt apart if the top needed cleaning, wash the top, put the wool batt back in and retie it. If the batt was in bad shape, it went to the woolen mill to be re-carded. They cleaned it that time and usually had to add some new wool, as there was always some of the old wool lost in the carding process. "Carding"? Using a wire-toothed brush to comb out fibers, as of wool, prior to spinning.
