Many of the replies are what I say. Relaxing, joy of making a project, keeping the arthritis away in the hands and the especially the mind being retired. It has always been a joy. When my Dad was alive, I had taught him how to crochet. We had many discussions on types of yarn, colors, what size hook needed, etc. He has been gone many years, but still have his hooks that he used. They are priceless to me.
