After two weeks I unwrapped the rust bundle. This experiment went well. This cloth originally was soaked in poke root. The rich berries turned the cloth to a bright purple. However when I rinsed it on the line it faded to a dull brown. Yuk. Then I wrapped it around some washers and rusty birds I picked up at an antique store. I added a tea bag to see what I might get. Here are the results of the experiment.
