you can use wool blankets for batting too---you just wash & dry the wool blanket first- i would wash & dry any blanket i was going to use- it is a great way to (recycle) old blankets that are no longer used/wanted/are worn- some people shop the thrift shops for old blankets just for that purpose- you can quilt them any way you want- or tie them without worry about them separating like batting- blankets make wonderful batts.
