There are several good companies, although not all have bulk chain
available. Ask specifically for chain that is not plated, because
some styles are rhodium plated. Here are the sources I have used:
Azur Global Imports, Downeast Trading Co., Rio Grande, Stuller, and
Blake Brothers. Most are wholesale companies.
No association other than a satisfied customer, yada, yada… Judy in
Kansas, where it continues to be a graceful, gradual cooling fall.
