Making things with recycled copper has been a hobby since my grandfather taught it to me decades ago.  Now it is time to refine my skills, and step it up a few notches.  I have also discovered, (selfishly I must add) that copper is a natural remedy to the almost crippling rheumatoid arthritis that I have had since my teen years.  The decrease in inflammation has also indirectly improved my asthma so I am less bothered by it!  Maybe it can help you too? Let me know if it does.  (or let me know if you have questions about this.  I have lots of documentation on it!)
