How Do you Wind Your Shuttles?

I get arthritis in my hands, and found that by the time I had wound a post shuttle, my thumb hurt too much to tat !!  I bought a shuttle winder from Tatting & Design and it has made a great difference to my hobby.  The cream jam jar type lid screws off and the shuttle opens, when slid in the hole in the middle. When screwed back on, it can be turned by the knarled nob at the other end of the spindle and the thread winds on the shuttle.  It has certainly helped me.
