I've recently tried rust dyeing for the first time. The results were sort of okay, but it's encouraged me to try some more in the future. Here's some photos of the bits of fabric I did.
We moved house last year so Murray cleaned out all the stuff from his shed including anything that was rusty. We managed to find a few nails and screws, and a couple of old drill bits. The first two photos used those.
Next I bought some cheap steel wool pads, and they really worked well because they rust so quickly. I'll definitely use those again. The second photo is most like the actual colour. Don't quite know what I'll do with them yet, but I had some fun experimenting.
