My mother made me a "Tumbling Blocks" Quilt from wool a gazillon years ago. It has flannel on the back. It has been used and used and used and showing no signs of wear. It has washed numerous times also. My sister makes a wool quilt for each of the neices and nephews that get married and they turn into favorites. She has used almost every pattern possible, and her advice is to use a pattern that doesn't have lots of seams intersecting at one place, i.e. don't use a star. My quilt is a really big one, and I just can express how wonderful it is. Even my wonderful husband doesn't like wool (scratchy), but he loves this fluffy warm quilt also because of the flannel on the back. Sara
