I don't know the type or brand of wool. It was a beautiful purple swing style coat and I loved it, Made me feel elegant when I wore it. Just said 100% wool and dryclean only. I have no idea why it linted so bad. From now on, I plan to start with the bucket and plunger for the first wash. My washer never even made it to the first spin on the wash cycle. I still am enthralled with the wool felting and yarn felting and the process. I just will be more careful in the future.
