there is an older boom (1970's) believe the title is The Wool Quilt. Is available on Amazon or Ebay. Gives all kinds of info about using wool.
Many many many years ago my aunts made wool lap robes as the cars were unheaqted. They were just squares.
This has been discussed here before and most agree that very thin batting should be used if wool is alwo on the back. However, I would tend to use another fabric that simulates wool but is thinner. And yes, they make wonderful warm quilts. Just have to respect the nature of the fabric such as fraying etc and perhaps make larger seams.
