Wool batting is wool sheered from sheep once a year. Then it must be taken care of in cleaning it. I`m sure there will be some one on this board that raises sheep. I use raise them, but only sold the wool. As a child I carted wool. You take clean new wool and put it between 2 wood squares (about 12" sq. )These boards have a handle on one side and many little spikes (nails) on the other. Then you pull the wool thru these nails many times till it is soft, fluffy and has no lumps. These blankets are so warm that the army issued them to their men in war. I have one my Dad used for hunting in winter, and one fluffy one that is new for at home when the lights go off in winter!
