I use a Lot of wool fabrics in my quilting, my favorite fiber to work with. First thing is Wash your wool, warm to hot water, some detergent, a regular cycle. Then toss into the dryer, again regular cycle settings. I generally take my wools out of the dryer before they are overly dry ( helps with wrinkles) then I just press them dry, but sometimes I don't catch them and they are fine. Then your wools are ready to use. Your finished quilt projects are washable, check out my (Backyard Gatherings) quilt... It has been washed, dried 3 or 4 times in the picture
