I love using wool also. One of the first quilts I made was from black/grey wool from coats at the thrift stores. I washed and felted it, cut it into different size squares and rectangles, hand embroidered a few primitive, large stitches flowers on each piece. Sewed them all together, backed with flannel and gave it to my son and his wife. They said it was so heavy they would be able to stay warm at the North Pole, but they loved it. I still buy all my wool at thrift stores. When I find a piece of really beautiful wool I am elated.
