I've made LOTS of wool quilts! I often use recycled wools from garments, I de-construct the clothing then wash all of my wools in hot, hot water, some detergent, rinse in cold water, tumble dry when it comes out it is ready for quilting. there are lots of websites, shops, designers who work with wools (you can see a picture of my wool on flannel 'backyard gathering' quilt here on the board.) some places to visit- Sue Spargo; Primitive gatherings; ' A couple of Sisters'; the Wooly Lady; once you start looking you will find lots of links for more- people are finding that working with wools is wonderful-and makes very luxurious fabulous quilts.
