The definition to revival is "a restoration to use". That is what is what I do with wool. After purchasing old wool sweaters and blankets, I wash them in HOT water and shrink them to child size. We have all done this by accident. After this I dry it in the dryer. This is call felting. Felted wool can be cut without freying because it is comprssed fibers. Each of my creations are made out of several different peices of wool, cut and peiced together to make a new sweater, mitten or scarf. Revival!
