I just made quilts for my year-old twin grandsons with Quilter's Dream wool batting and they washed up beautifully when they were done. I used a warm wash and warm dry on my regular washer setting, because I knew they were going to be washed a lot and I wanted to be sure they could handle it, without needing any special care.
I also made a queen size quilt for my oldest son with the same batting, and washed/dried it in a big washer at the laundromat, warm wash, warm dry.
They all came out very cuddly and soft too, with no real shrinkage that I could see.
