Loren Damewood has been creating intricate decorative knots in precious metal for over 25 years, and recently retired from a career in the aerospace industry ("Not exactly rocket science... more like rocket tech.") to teach workshops on his methods full time. He taught himself the techniques he uses, by trial and error, and delights in helping others to bypass the painful and tedious stages and go right to the shiny stuff.
You can learn more about his amazing artwork at his website: Golden Knots.
