I have been working on surface design with rust for a few years, but have stepped up my interest over the last year. I was wanting to come up with ways to mimic specific patterns and hit a road block. I took photos of rusty grain bins, signage, and other grange equipment and wanted some companion fabrics.
So, I made thermofax screens from the photos.
I used iron in print paste and thermofax screens and I was off getting great companion fabrics!
I am working with resists and iron powder now and also getting wonderful results. I am also working on a huge piece of fabric using our fire pit cover to rust since it has wonderful patterning. More on this piece later. As the rusting is just the first layer of surface design.
