I love this piece of fabric! I have wanted to try rust dying for a while and the other day I was rummaging through my husbands shop and found a few chains and bolts that were good candidates for the experiment. I took a piece of PFD fabric wet it and wrung it out. Then I soaked it in vinegar and wrung it again. I then wrapped the rusty objects in the fabric and put the whole thing in a plastic garbage bag, squished the air out and tightly closed it. I let this set for about 2 1/2 days. I then rinsed it in salt water (I read somewhere that that stops the rusting process) and let the fabric dry. Finally I ran it through the washer, dried it and ironed it. I really thought that the color would fade when I washed this and was amazed how it did not. I will definitely do this again.
